So there used to be this popular Vimeo Project called Me Right Now. Its easy; take a video of what you are doing RIGHT NOW, then upload it to Vimeo and tag it with MeRightNow.
Its kinda twittery, but its a cool way for you and your friends to keep track of what you're doing.
Then add it to the Me Right Now project forum here: vimeo.com/forums/topic:1587
What are you doing right now?
