The link above is a really informative read on Facebook. Aside from the privacy issues that bother me, I really like what Virani says about the argument for FB being a great way to communicate with friends and family. Turns out, it's not a good tool at all:
...there's a big disconnect between your expectations when you communicate on Facebook and what really happens. Basically, Facebook filters out your posts based on whether or not people will use Facebook more if they don't see it.
It feels like Facebook is the only way to stay in touch. Through pictures and comments. It feels like everyone's on there and you're getting a good feed on their life.
In reality, lots of your posts are never seen by anyone! And you miss out on their stuff too. Even if your friends' stuff gets to you fine, it doesn't mean your stuff gets to them.
