I just tried it out a bit and I must say that I think it has potential.

Small change I recommend: make the "Add photos and post" button more visible. Now you have to put the cursor in the post field for it to become visible.

I wish you all the luck.

Thanks! This was a preview version to get the site out and bang at it. We have a new version that will address a lot of these interface on ramp issues.
