The homepage is so clean and compelling that I scrolled down to learn more, causing me to miss the "About" link in the primary nav and use the learn more links on the bottom of each page. That might not be typical of most people browsing the site, so take my advice with a grain of salt.

In hindsight, maybe it just needs something snappy like "It's like a CMS for your next social app" (or an equivalent analogy), like startups coming out of YC often do for demo day. "An open platform for social apps" made me pause a bit too long because it's a relatively new concept.

I signed up for Beta access. One minor discomfort and some friendly advice: The thank you text says "Thanks for joining the brotherhood". You might want to stay away from language that's exclusionary to 50% of the population, and a great majority of social media users, even if it's solely intended as fun, jocular page copy.
