Thought this would be of interest to people here:

It's what i've been up to since BitInstant went down, beta will be coming around the end of april and there's a fundraiser on littlebitback with some more info:
https://www.littlebitback.com/friendcrypt-encrypted-social-networking/

As the littlebitback page says, depending on response to the fundraiser it'll either be funded by donations or via a freemium model. What I absolutely do not want to do is make it advertiser-funded as that opens up privacy risks.

If anyone is interested in helping out more directly, get in touch via PM.
