Comments
Ok, if this is working, it should now be possible to comment on posts here.
I was a bit slow in trying this out, because I had a hellish time setting up the blog in the first place, and I expected adding comments support with Disqus would be just as hard, but if this is working, it was a simple matter of adding
disqusShortname = "r-programmer-blog"
to the configuration file and telling Disqus about the existence of the blog.
Cool.
