For WebODF, we also use GitHub because WebODF is a JavaScript project and there are many JavaScript programmers on GitHub. I'm also a member of the KDE community as is boud with the Krita project. But KDE was traditionally more a C++ community. That is becoming more diverse now.

I agree with all the points in the blog, which is why I posted it. But moving WebODF to a separate server would remove a lot of the easy of accepting contributions, so we're not doing that at the moment.
