Sorry if I sound like an ass-hat but how do I know you aren't collecting email addresses simply for selling to a spammer? There is nothing on your site that explains what your product does. Heck, there isn't even the standard disclaimer that you won't sell my address to spammers!

I understand the need to keep your idea secret until you launch but I don't understand the need to keep potential users completely in the dark.

The only clue I have to go on is the fish-eyed alphabetical column on the left which makes me think it must have something to do with the contact list. - are you selling me an intelligent PIM, maybe?
