We're "launching" our LaunchRock page on Monday - http://www.onsidekick.com.

A semi-related question to this that we're struggling is: how much should we bother incentivizing those who invite the most with cash, an iPad, or even a contribution to their favorite charity? At the end of the day, this sign-up isn't really directly for people who are going to purchase our service in the future. It's really just a way for people to say "hey, I'm curious - let me know more". We're struggling to determine how much that is really worth.
