What is keeping Facebook alive? It's, what, 7 years now..? In Internet years, it's ancient.
Why? Because it's so bloody useful. It has so many good features and I don't see anyone coming up with a better system for now. And don't be like, "oh facebook? f**k that, I don't even use it". It's damn useful. It's a better way to stay in touch with some of your older friends. Reasons why facebook changed my life:
1. Sharing events is much easier. You no longer need to call people and tell them, hey man, there's this party downtown.. Now you do it with just one button.
2. You no longer need to send your friends photographs. Just share them on facebook.
3. Good tool for discussing current events.
4.
Stalking on girls is easier than ever Hmmm, getting interesting info about people is easier than ever.
5. Entertainment. Lots of funny groups to follow.
6. Studying. We have groups on facebook used for discussing college assignments. Very useful.
*. Games. Never play them, still think they're worth being mentioned.
All in all, facebook is a great tool. If membership cost money, I'm sure many people would have paid.
