1. Good point; I'm not really sure where I was going with this now; GitHub and another CDN are basically the same. I must've been distracted while replying!

2. Yeah, it's not ideal. In this case, it looks like Disqus are gonna fix stuff though (they've commented on my post; there's a link right at the top of the article now).

3. I don't have access to the server logs as I'm running on GitHub Pages, so something like Analytics is all I have. I do find it useful (given no server logs), it's nice to see the traffic to my blog; there's no point posting if nobody is reading! :-)
