I made a quick addition to the commenting system. You can now subscribe to an RSS feed for individual comments threads. All replies will appear in your RSS reader, like so (in the case of Google Reader):

The formatting is a bit rough, but it should be easier to keep up with replies this way. You can view the full body of the comment within the RSS feed, but in order reply you'll of course have to jump over to the site.

If you read this site regularly, you'll know that the comments periodically (about once a day) get spammed to death by wholesellers with hilarious English. While I delete the spam quickly, I have yet to implement a system for preventing it in the first place. However, I have put together something totally unscientific that should keep the comments RSS feeds free of the spam.

To subscribe to the feeds, click the RSS link next to the comments thread:

The RSS icon should also appear in your browser's URL bar.
