Can’t decide on site content until it has a name. Can’t give it a name until decide on content so name will reflect it. I’m reminded of that episode of Star Trek with Harry Mud. Maybe you need a name that reflects recursion or a Catch-22.
Your current list is good, but the only stand out is stackoverflow.com.
If your goal is to have the best site to visit for software developers, I would recommend primaryfunction.com. (It is currently taken and redirects to a blog)
I would go with a crazily-named, Web 2.0 site. The question to my mind is, how does a user find your site via the google search bar? What will they see if they type in “private void” or “stack overflow”? Just call it oinkyboinky and be assured of the #1 result in a search
What about something like codingrocks.com? I just checked and it’s still available and most developers experience the “coding rocks” phenomenon frequently.
