RSS and <description> tag
Looking at the KB article, it suggests using the "teaser" for the RSS <description> tag for each <item>. The problem with this is if you put any links in here (as might be common for a link to the full article). The links that go into the RSS tag should, I think, be full links, not relative.
The "full path" problem seems to be cropping up in a number of different ways.
I think at this point, I'm just going to go ahead and use one of the "extra" fields for my RSS description. Really all I need to do is remove the link to the article itself from the teaser (as the RSS <link> elements provides the necessary link), and then just be careful when I occasionally cross-link from the teaser of one article to the body of another.
I just ran into the same thing on my site (on which I recently added an RSS feed). In fact, the RSS feed from Joel's site has the same problem as well.
