The best of the Facebook-like social networks right now is Friendfeed, I think.
FriendFeed helps you discover and discuss interesting stuff that your friends and family find on the web.

I’m experimenting posting my own Friendfeed on this site. Scroll down to the bottom of the navigation if you want to check out my own contributions. All my blog posts, photos, videos, etc. will appear there in a chronological order from most recent to oldest.
I don’t have many Friendfeed friends as yet. There’s no telling whether this service will survive. Facebook could easily swallow this and the other social networkds over the coming years.
