Berhubung dengan profesi impian saya sebagai penulis novel dan hobi saya yang suka menulis dengan ballpoint gel :p saya menemukan salah satu sifat tinta gel yang ternyata sensitif terhadap panas (maksudnya : bisa terserap oleh panas). Sedangkan panas itu bisa didapatkan dengan gampangnya (dengan cara yang simpel) contohnya dengan gesekan atau yang sering dikenal dengan friction.

Sekarang, kaitkan dengan hobi saya yang suka menulis. Disaat saya menulis, saya tidak mungkin menulis benar seluruhnya (pasti ada salahnya). Biasanya supaya tidak ribet/ tidak repot, jika ada kalimat atau kata yang salah, saya hanya mencorat-coretnya (ngurek-ngurek) atau menutupinya dengan Tip-Ex. Tapi, jika dilihat-lihat lagi, tentu saja kertas tempat saya menulis menjadi jelek dan tidak enak at kalau terdapat banyak bekas Tip-Ex atau coretan.

Jadi, saya punya rancangan bagaimana jika kita merancang suatu alat yang tidak butuh bahan dasar yang terlalu mahal dan bisa digunakan untuk menghapus atau menghilangkan kata dan kalimat yang tertulis dari ballpoint gel itu dengan menggeseknya.

Facebook, mungkin sudah tidak asing lagi bagi sebagian besar orang. Ya, facebook adalah salah satu situs jejaring sosial yang sangat digemari masyarakat saat ini. Mulai dari anak - anak sampai orang tua, siswa sampai mahasiswa, tukang bakso sampai direktur utama, pedangang kecil sampai pengusaha, dan sebagainya. Dan sudah sewajarnya, setiap teknologi baru, apapun bentuknya, pasti mempunyai dampak positif dan negatif. Begitu juga dengan facebook, punya dampak positif dan negatif juga. Berikut ini beberapa dampak positif dan negatif dari penggunaan facebook menurut pengamatanku :

Dampak Positif :
Mempererat silaturahmi
Ya, mungkin ini adalah kegunaan dari facebook yang paling bisa kita rasakan. Bahkan dengan facebook, kita bisa menemukan kembali orang - orang yang pernah kita kenal di masa lalu.

Mengetahui potensi diri
Dalam facebook banyak terdapat kuis yang bermanfaat untuk mengetahui lebih banyak tentang siapa sih kita sebenarnya. Namun, kita juga harus tetap waspada, sebagian kuis yang terdapat dalam facebook mengandung unsur - unsur ramalan, dan sudah tentu anda paham bahwa percaya pada ramalan merupakan sebuah kesyirikan, dosa besar yang tidak akan diampuni oleh Allah ta'ala :D.

Media promosi
Jelas, facebook bisa digunakan sebagai media promosi, entah itu mempromosikan produk, jasa, instansi, atau hal lain. Bahkan, pada saat pemilu legislatif kemarin, sebagian caleg juga menggunakan facebook untuk media kampanyenya.

Sarana diskusi
Di facebook kita bisa bergabung dengan berbagai komunitas / grup.

Tempat curhat
Hmmm, yang ini mungkin bisa juga, kalau kita lagi dapet masalah, kita tinggal mengupdate status facebook kita dengan masalah yang sedang kita hadapi, ntar kalau ada orang yang peduli, pasti orang tersebut bakal memberi komen yang isinya mungkin cuma sekedar memberi semangat atau bahkan memberikan alternatif untuk menyelesaikan masalah. Tapi tempat curhat terbaik tetap, Allah swt, yang bisa menunjukkan jalan keluar atas setiap masalah yang kita hadapi. Betul ??? hehe.


Dampak Negatif :

Lebih banyak waktu kita yang terbuang sia - sia untuk hal yang kurang bermanfaat
Apa lagi kalau sudah kena sindrom facebookholic alias kecanduan.

Boros duit
Hmm, yang ini tentu tidak bisa dihindari, apalagi yang facebookannya pakai hape, lagi seneng - seneng facebookan, e tau - tau pulsanya sekarat ( Pengalaman pribadi, hehe ).

Malas belajar, mengerjakan tugas atau pekerjaan yang seharusnya kita kerjakan
La wong facebookan terus, akibatnya secara tidak langsung, kita mengalami apa yang namanya... pembodohan yang menyenangkan.

Memicu terjadinya pergaulan bebas tanpa batas.
Ya, namanya juga dunia maya, dunia tanpa batas, seseorang bisa menjelma menjadi siapa saja dan berbuat apa saja, baik atau buruk

Hmmm, menurutku mungkin baru beberapa hal itu saja dampak positif dan negatif penggunaan facebook, silakan kalau ada yang mau menambahkan. Pesanku, gunakan teknologi baru dengan sebaik - baiknya untuk melakukan perbuatan - perbuatan yang baik, bermanfaat, dan tidak merugikan diri sendiri atau orang lain. Semoga bermanfaat :D

Plurk is a free social networking and micro-blogging service that allows users to send updates (otherwise known as plurks) through short messages or links, which can be up to 140 text characters in length.

Updates are then shown on the user's home page using a timeline which lists all the updates received in chronological order, and delivered to other users who have signed up to receive them. Users can respond to other users' updates from their timeline through the Plurk.com website, by instant messaging, or by text messaging.

Plurk is very popular in Taiwan, Philippines, Indonesia and the United States. According to Alexa, as of February 11, 2010 (2010 -02-11)[update], 34.4% of Plurk's traffic comes from Taiwan, and about 30% of Plurk's traffic comes from Southeast Asia.[3] Plurk is also ranked 24th in Taiwan and 1,062nd worldwide.[3]

Twitter is a social networking and microblogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author's profile page and delivered to the author's subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access. Since late 2009, users can follow lists of authors instead of following individual authors.[4][5] All users can send and receive tweets via the Twitter website, Short Message Service (SMS), or external applications (notably including those developed for smartphones). While the service itself costs nothing to use, accessing it through SMS may incur phone service provider fees. The website currently has more than 100 million active users worldwide.[6]

Since its creation in 2006 by Jack Dorsey, Twitter has gained notability and popularity worldwide. It is sometimes described as "SMS of the Internet."[7] The use of Twitter's application programming interface for sending and receiving text messages by other applications often eclipses direct use of Twitter.

What we have to do is deliver to people the best and freshest most relevant information possible. We think of Twitter as it's not a social network, but it's an information network. It tells people what they care about as it is happening in the world.

Facebook is a social networking website that is operated and privately owned by Facebook, Inc.Since September 2006, anyone over the age of 13 with a valid e-mail address can become a Facebook user. Facebook's target audience is more for an adult demographic than a youth demographic.Users can add friends and send them messages, and update their personal profiles to notify friends about themselves. Additionally, users can join networks organized by workplace, school, or college. The website's name stems from the colloquial name of books given to students at the start of the academic year by university administrations in the US with the intention of helping students to get to know each other better.

Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes. The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It later expanded further to include (potentially) any university student, then high school students, and, finally, to anyone aged 13 and over. The website currently has more than 400 million active users worldwide.

The original concept for Facebook was borrowed from a product produced by Zuckerberg's prep school Phillips Exeter Academy which for decades published and distributed a printed manual of all students and faculty, unofficially called the "face book".

Facebook has met with some controversy. It has been blocked intermittently in several countries including Syria, China, Vietnam, and Iran. It has also been banned at many places of work to discourage employees from wasting time using the service.

Privacy has also been an issue, and it has been compromised several times. Facebook settled a lawsuit regarding claims over source code and intellectual property.The site has also been involved in controversy over the sale of fans and friends.

A January 2009 Compete.com study ranked Facebook as the most used social network by worldwide monthly active users, followed by MySpace.Entertainment Weekly put it on its end-of-the-decade 'best-of' list, saying, "How on earth did we stalk our exes, remember our co-workers' birthdays, bug our friends, and play a rousing game of Scrabulous before Facebook?"

There have recently been reports of Facebook proposing an initial public offering (IPO), i.e. issue equity shares as stock to investors. However, Zuckerberg stresses that it will not be for a few more years, and the company is in no need of additional capital. Also, some analysts fear the Facebook IPO might be a particularly weak one.
