For me myself the answer is an emphatic no. I have an account with like 25 friends. Ignore requests from the people I did not like in HS. Play 0 games there, & upload nothing but a few basic pictures there. Sign in nowhere online with my Facebook account except Facebook. I mean why the hell do I want anyone to know what I am doing when i am online? It is none of their business. What I say at a site about politics, or cooking, or winning high score on a stupid video game. Why do I want people to know this? I don't.. It's not important & none of their business unless I share it with them. If I do I can create a blog as fast as a flash & share a simple link. I especially don't want anyone business related to know anything. People are evil-spirited & self-centered by nature & will use any edge to make you look bad so that they will prosper. On top of this I am just donating my time & clicks as revenue for a stupid facebook referrer. I would rather support a site that needs the hits & clicks & not Facebook There are 3 big reasons for me NOT to have FB at the center of my online experience. 1. Security. No Thanks for this http://www.skullsecurity.org/blog/?p=887 Or This http://www.pcworld.com/article/205295/gang_uses_facebook_to_rob_houses.html 2. The internet is for exploration isn't it? This is dumbed down by just sitting on a facebook page & doing everything from that page. 3. What Facebook does offer are just weak imitations of what is better. Linkedin for real social contacts that can actually matter. I mean just about any photo sharing site... Smugmug, Flickr, Webshots from the top of my head. About 20-30 gaming communities, with everything from flash games & casual games to full blown mmorpg communities. If I really want to know how my real friends are doing I pick up a phone. Facebook is GOOD for one thing only. Finding people from the past that you want to find. That about ends any of the usefulness of it for me.
