I would only argue one point in this: Github is not a developer's paradise. It's good. In fact, it's really good. But it has one huge weakness, something which all DVCS repositories seem to have followed: they charge per repository.

This is a terrible pricing model. It should, if anything, be based on per-GB of storage regardless of repositories. Otherwise it gets hideously expensive for people to, say, have many small repositories.

It just doesn't make sense that, say, the Linux kernel, and a 500 line personal Ruby project are equal units as far as Github is concerned.
