InviteShare.com can help you get in on all those hot private betas you’ve been missing. The concept is simple: Users who want invites post a request online. Users with extra invites send them out. The more invites users share, the higher they move on the beta invite waiting lists they’ve signed up for.

There’s a lot of buzz around InviteShare at the moment, which means competition is pretty stiff for the best invites. But the service is free, so there’s really nothing to lose. InviteShare is currently handling invites for the following betas:
