Slightly off-putting that I have to enter my email before I can even see what this is/does. All I see is "social network"; how does that translate into collaboration tools? Perhaps some pre-signup screenshots, videos, or even an FAQ.

I don't want to give out my email to every website just to get to page 1.

What advantage is this going to have over Startup Guild[1]?

Any ideas are welcome!
