http://uCrypto.coI'm not affiliated with the guy running the site, but I just joined and we don't have many users yet since it just launched yesterday.
Anyway I'm pretty impressed, I've never been into Twitter and I don't much care for Facebook, but this one is specifically for the crypto community. I like it, and it's already starting to be fun.
After immediately being accused of trying to harvest our email addresses to sell Viagra, the owner explained that he decided to make uCrypto after Facebook banned him for 30 days because he posted a Bitcoin logo and it was flagged as terrorism. He has a good point; Facebook is too powerful, and it isn't that great IMO if you just want Crypto updates. Besides, Facebook founder Mark Zuckerberg is on the record as saying "They trust me with their information for some reason. Dumb fucks." source: (
