Registration went smooth. I don't particularly like being asked to frequently to invite my friends. Specially considering that if I am registering it means I have never tried your product so I do not have anything to suggest yet, so I will not do it. If you must ask me, ask me after I tried your product for some time. Make sure I like it, other way it's just annoying.

You left some "debugger;" in the js files. I randomly stumbled upon one.
Overall not too bad but I think it will be quite hard to make it catch on.
I would suggest those that are interested on understanding our concept better to access some of our internal pages:
