(to question 1...) It's worth considering that if you're an enterprise then you* might not actually want a constant stream of new releases to deal with. Where you = the CTO/CIO/Security/VP Operations, and the purchase decision maker. Many enterprises are (still) anally retentive about acceptance testing any new version from a vendor. You = the engineer definitely do, but sadly in the enterprise world the engineer isn't the customer. Oh, and don't shoot the messenger. I'm not saying I agree with that status quo, simply that if GitHub aspires to make a decent revenue stream from the Enterprise then they'll have to work to those kinds of dynamics.
