That's how I feel about LEDs :) Can't understand for the life of me what the attraction is :)
Facebook is useful for some things, there's a lot of flotsam floating around that you need to ignore or block. I don't want to join your mafia, or have a virtual farm and be your neighbor. But, perhaps I *am* interested in the pinball you're working on now - or I do care that my favorite band is coming to town.
I get to see photos of my niece and nephews a few times a week, instead of once or twice a year. I've reconnected with lots of old friends. Perhaps they became old friends for a reason, and in some cases, I'm sure that's accurate, but I still see some value to it.
I don't see why it'd be hard to leave facebook - pretty easy to delete your account if you want to!
Yes, there's a lot of wasted time on there. Just like there's a lot of wasted time on smoke breaks for coworkers, or watercooler banter. Some folks will gossip, whether they are behind a keyboard, or running into an old friend at the grocery store.
Many of my facebook friends are pinball folks, too.
Hey, you could apply many of the comments about Facebook to any internet site. Some folks spend too much time reading on wikipedia. Some folks spend too much time on RGP.
