I’ve been having problems with the cache of the RSS 2 feeds, and in an attempt to clean up config files, broke it completely. Whoops. As a matter of record, though, I think that I would recommend the Atom feed above the RSS ones, after doing a little reading on the two. Personally, I’d like to ditch RSS 2 completely, especially if the issues persist (which I can’t really explain too well, and it might just be a problem with my reader — anyone else having problems?), but we’ll see what happens.
I should probably elaborate what’s happening. Using liferea, with the RSS 2.0 feed for Planet Larry, the posts from ~5 days ago always refresh as “new” posts. It’s really odd, especially since it’s the only one of all my feeds that does it, and of all the ones on Planet Larry, it’s just the RSS 2 one that is doing it. The Atom one is fine. Who knows. It could just be a bug.
