I tried it when it was first announced, so the experience has probably been smoothed over a lot since then. It has the steepest learning curve of any nosql database I've tried so far, but perhaps for people with more Map/Reduce familiarity that won't be the case. The biggest hangup was that Map/Reduce queries could only be written in Erlang, but now it seems they can be written in JavaScript too. That'll be a nice improvement. The installation was a bit less straightforward than I would have liked, but it seemed to work fine after that. I ended up going back to Redis, because I don't actually own enough hardware to make Riak worth using.
