Check out [[http://www.ning.com/|Ning]]. They have made the next step in bringing web based apps to the user — by letting anyone create any app. Its pretty neat. You can create your own craigs list, or match.com or hot-or-not or any of the [[http://appideas.ning.com/|tons of ideas]] that Ning gives you. Or, just go and build something new.
I think its pretty cool. Exciting times.
