This looks like a really great coin to start investing into it. The only thing is only being actively traded on a single exchange which is Bittrex, but as long as it keeps alive on that market, then it should be no issue.
I'm always on the lookout for hybrid PoW/PoS coins so I will give TeslaCoin a shot. Still, I wonder if the dev is still active or the community has taken over?

Nevertheless, I'm looking forward to support this coin for the long term.

As tiredofscams and crysx explained, we're here and working behind the scenes.
