I like this idea, good pitch on the page, but it's absolutely critical that it just works. I installed it, opened it, at first it wasn't obvious if I had to make an account, use an existing service, or what, but I finally noticed the create an account and tried to make account in which it says couldn't connect with video server, I tried again and it says account already registered with no apparent change in the form.

After this I closed out, and under any other circumstances I'll never go back and try again. GChat seems to solve this problem for me already but I was tempted to try this out but it just didn't work with the flow and interaction on the first try and to me that's a deal breaker.

So tl;dr for you and anyone else, your product has to absolutely work and must initially make sense flow wise for your first time users. Especially if you're in a market that has many other solutions because getting me to go back find the application and try again sometime in the future is going to be really hard.
