There was a lot of positive coverage when things were taking off in late May-early June, then this Quora post got a lot of play on reddit, Hacker News, and the like.  I don't agree with his harsh all-or-nothing rhetoric and labeling it a "scam", but he does make a few good points about security and the like.

I sent them a MoneyPak last night, and received BTC this morning according to blockexplorer (I haven't finished downloading the latest block chain yet).  Just reporting a positive experience.
