This is what Sourceforge did too, and they still had the DevShare adware thing didn't they?

GitHub is great -- huge fan. To some degree they "sold out" to Microsoft and things could have gone more south, but thankfully Microsoft has ruled them with a very kind hand, and overall I'm extremely happy with the way they've handled it.

I guess I always retain a bit of skepticism with such things, and the long-term viability and goodness of such things never feels totally sure.
