Interesting. BitShares is more business centric while they seem to want to build stuff around social networking. In the future both communities although with different objectives, could complement and learn a lot from each other.
Dash seems to get more and more interesting but I just can't seem to get over their distribution. Maybe because I missed the train? Idk, but that instamine puts me off.
Also, I have a question, how does BitShares Stealth Transactions compare to Dash's anonymity? That would give an interesting blog post!
