Troubles with posting comments on this blog

Looks like the problems with posting comments on this blog have been related to the browser. Specifically, Internet Explorer 9 seems to be incompatible with a particular way commenting was set up. I have not been using IE for long time, which is why I could not reproduce the problem. I have changed the commenting set up and have posted a comment from IE9 successfully. Please give the blog another try and let me know if you are still having problems.
