For me the main uses of FB are now:
1) Rolodex of friends, with reminders from the ones who actually use it.
2) Bad version of stumbleupon. Seriously large amount of unuseful content, but it does kick up something interesting now and again.
3) Reasonable funnies stream. There's always someone with a good meme.
There's no real content though. All the news commentary is simply terrible. Loads of people trying to be funny. An enormous number of flamewars. Very few people who know anything at all, not just in politics but science as well. The actually insightful comments are drowned out completely.
Other things:
- Loads of comments are just people tagging a friend so they see an article. FB could fix this very easily, I don't really care if Richard Head wants his friend James Smith to see some article.
- Autoplay videos are annoying
- Obvious parasite accounts aren't dealt with. I know my dad hasn't started a new account with the same pic and added me. Do something about it.
All in all, I'm not sure FB would have become FB if its product was what it is now 10 yers ago.
