Interesting Beta Websites and Applications

Beta websites are intriguing and may get you cool stuff if you get in early.  Many years ago I was able to get in early into the Grand Central beta - I entered my name and email on the sign up list and a month or two later I received an invite to a telephone application that was purchase by Google before it ever.  I'm always on the lookout for new and innovative beta websites.  I've listed a few below that seem intriguing:

VoteIt:  VoteIt makes group decisions easy. Trade in your spammed inbox for fast, clear and fun group decisions. Finally, there's a way to bring all sides together.

JoynMe:  JoynMe makes it easier to get people together for impromptu events and activities.  It looks very interesting and I can see how this would be very valuable to use. But the question is who would use this?

PostPiks : PostPiks is a photo sharing website and mobile app that allows you to share photos with your social circles.  Though postpiiks is still in beta, it looks intriguing for a new photo sharing site..

Capsule:  Capsule is an event planning website established to help people plan, share, and remember group experiences.

PayCento :  Paycento is a micropayment platform from 10 cents onwards providing both virtual and real currencies. It engages with social networks to make small payments in a simple fashion

Bebo: Bebaloo simplifies your Facebook fan analysis — engage and reward your fans. With Babaloo you can strengthen your relationship with your fans and you can analyze the topics most discussed, the top links and all users who have more influence on your page.

CancerMom : Cancermom is a website dedicated to socially bringing together people both with cancer and those who are close to people who have cancer. 

iAdmit : A little like twitter, iAdmit is trying to be more of an anonymous friend that you can tell your secrets to.  Its a neat idea, however, I'm curious if people would be willing to give up their secrets to strangers at iAdmit.

I imagine that there are many more beta websites out there that seem like they have what it takes to take it to the next level.  What other ones do you think we should add?
