Seems I got bitten by this bug in the Comment RSS module for Drupal on my anime blog site. Technorati seems to be picking up the comments instead of the actual posts from the site, and I'm sure there's other aggregating systems that are doing the same when trying to automatically find the default RSS feed for the site. Looking in the source code for the blog shows that the Comment RSS feed is linked before the frontpage RSS, causing this issue.
I hope I can get some time to work on a patch for it this weekend.
