Kickstarter's had a very impressive rise prior to Diaspora. They had over a quarter million UVs in March according to compete (http://siteanalytics.compete.com/kickstarter.com/), up 100% over the prior month. With a quick look at the site to can see lots of ~$10k project are getting funded all the time. That's revolutionary.
In my original post, I acknowledged Fundable had bigger problems: Now it’s important not to overlook all the other things that might have caused one business to succeed where another failed. If you google “Fundable” you’ll see they made a number of execution missteps. Fundable also didn’t have the advantage of launching in a time when high quality video creation is so easy and sharing is so powerful over platforms such as Twitter and, well, Facebook. Nevertheless, it’s great to see a venture that’s executed well and in Kickstarter’s case its competency certainly extends to its design.
