Looking for feedback for my new web app w3frm.com

Sorry its very minimal - I wanted a proof of concept before I started adding more features.

I suspect that 99% of you will think its idiotic, but that leaves 1%, and its got viral built in, so it might develop a happy user base.

There are two ways a new user will approach this app. They could hit the front page, where they are asked to create a new accout, that's http://w3frm.com

Or more likely they could have been invited by somebody else with an invitation URL, inviting them to a specific "group". I've created a group called "First impressions". The invite URL is here http://w3frm.com/invitation/bcc74050-fa63-490a-a8c9-8ce735cb9b81

You don't have to enter your real email address if you don't want, that would only be required for forgotten passwords and notifications.

Don't overlook the bookmarklet, I think its critical to the user experience.

There's a very minimal api for browser plugins if anybody is interested.
