Came across this site/firefox extension recently and have quickly become a big fan. StumbleUpon.com offers users a way to rate sites, add tags, share with peers and paticipate in their community blogs.

Seems they have quickly become a site to watch. While I’ve only recently come across it, I’m already addicted. We’ll see whether it becomes annoying after a while or truly a worthwhile venture.

An interesting concept worth having a look at. Might be a solid replacement for all those bloody social networking sites we’re being forced to join.
