Joyent is doing FAN-TASTIC!
Their OpenSolaris fork is a dud, nobody is using their products, they don't even register on the radar screen in terms of cloud computing providers, and their service generally sucks.
Oh, and their CTO just quit, because he wants to pursue some new and interesting ideas, on a different cloud perhaps.
Not to worry, this is all part of their business plan. This IPO is going to ex-plooooooode, Dude!
