This is interesting, but for me the barrier to entry is too high for me to try it out absent an urgent need. Right now I'm thinking about visiting family sometime this summer and want to figure out the best time, so some sort of joint calendar might be good. But I can solve this problem adequately the usual way. I read through the front page and thought, "Oh, maybe!" But then I got to "Sign up or log in" and that was enough of a barrier that I closed the window. The way to get me to take the next step would be to let me try the product anonymously, with just a unique link. Maybe a link that I can forward, as with Google Docs, to anybody I want to be involved. If I find it useful, then I'd be much more willing to jump through signup and account-linking hoops.
