Posterous... Why aren't you using it yet?

Seriously. Posterous has made sharing whatever you want, wherever you want, incredibly easy. If you can send an email, you've already mastered Posterous. Check out their FAQ and this video for more info.
There's an app for that, too... If that's your thing.
And Posterous isn't just for blogs. Create groups (public or private) or events to capture posts from all your guests. The people behind Posterous are friendly and helpful, and they keep adding more cool features as time goes on.
