Is BlueMix a Heroku competitor or compliment? I want to develop on the Watson API but I also want to use a stack I'm familiar with. Also, do you have range estimates for the price of accessing the Watson API?
I went for an info session and a few events for Watson a couple of months ago at the IBM office in NYC. They are doing pricing with revenue shares. A lot of devs, including myself, were not happy about this. They basically were not open to projects that weren't directly making money off of Watson...
