Some folks have emailed me claiming that they can't leave comments for some reason. I'm very sorry for this. The discussions at Disqus seems to be centered around problems with Internet Explorer 7. I use and recommend Mozilla Firefox. I will continue to investigate this issue, but hope that the folks at Disqus will come up with a solution. Disqus is a nice format for comments but if a lot of you aren't able to use then I will chuck it.
