Julia is an extremely ambitious project -- more so than most other languages being developed now, due to the number of things they're trying to do, and the novelty of Julia relative to previous projects. I used Julia for a couple of toy projects, but I then started running into various odd bugs in the language and libraries, so I stopped using it.

It's great news for me that they're starting a company, and the core developers will have the opportunity to step up development as part of their livelihood. I hope they hire some full-time developers to iron out all of the kinks.
