It might be better to fight for diversity, but I was pointing out the actuality of it all. Networks effects are real, and this isn't the project I want to see die because of it.

I don't really understand this. Is there much more to it than a new login in terms of network effects?

So, github is the daily workflow for many people. You're in it, your around it, your using it. It's kind of the same as out-of-sight, out-of-mind.

If I want to, I can signup for yet another site and do git-things with this codebase, but I have to change my daily process to include a one-off change to a new location. There are real costs with this mental flow change.

I don't really see the downside. The providers seem pretty similar, and I can have more than one tab open on my browser.

But thanks for the explanation; I don't feel it myself but it's good to know!
