I had a problem with Github user pages for the past few months: It stopped building.
At first I was more than happy that for every commits, I can see the changes immediately, but after few days, it just keep showing the old build. I even started a fresh new accounts and setup a new user page, same thing happened. I tried many things to make it work, adding/removing CNAME, changing the page content, even waiting for few days, no luck. Tried to contact the Github team (via Twitter and the Contact Us page), no respond.
Now I am using my shared VPS to host a static site, waiting for some good news about build reliability, until then I wouldn't recommend using Github user pages.
Oh and by the way, if you set a CNAME, you wouldn't be able to access your project pages without adding it as a submodule into your user page.
I put up a static page a couple of weeks ago with no issue. Granted, I'm not using Jekyll and just generating the static files on my own locally before committing / pushing.
Hmm, strange symptoms. I haven't any issues like this. I've been using github pages + CNAME + gh-pages as project pages together for over a year without any issues whatsoever. Didn't have to worry about submodules either. Not sure why you're into these issues, kecebongsoft. I've used Jekyll as well as plain old html. I'm sorry you've had issues like this but I wouldn't discourage people from trying it either.
