My main point of feedback would be: why would I want to meet the 'right' people in my neighbourhood? What is 'right' anyway?

It is a question you answer further down the page, but I just barely got to that point. The design mostly focuses on how you try to solve a problem when to me as a visitor I don't even know the problem I'm having.

Furthermore, I am not entirely sure what you want me to do here. I think you want me to sign-up for an invite, but the call to action to do that is down below and not clearly visible.

The "Say YO!" button near the bottom of the page looks like an illustration due to the previous content blocks and I wouldn't have expected it to be the desired call to action. Perhaps even rephrase it to just say "Request an invite" and drop the "Have ideas?" part as that just gives someone another reason not to spend 30 seconds and not to complete the process.

Add a call to action to the lightbox showing the video. Else you're asking me to close the lightbox first and then look for whatever you're trying me to do.

I would reorganize the left hand side navigation as I think it greatly takes the attention away from the main pitch.

Remove the poll. Surely number of sign-ups is a good indication of people thinking your service is going to be useful?

Remove the cat and the text below it. Nobody is going to read that.

Hope that helps a bit. Good luck!
