I just noticed that this blog's RSS feed was pointing to my server's internal IP address, "hh2k.homelinux.org". Apparently it's a bug of some sort in subText's URL processor, so I replaced the dynamic link to the feed with a static one pointing to my DynDNS name. The feed should be working outside of my LAN now.
Has anybody been using the W3C Markup Validator recently? I ran my blog through it and received 24 errors in the output. Upon correcting one of the errors, the error count decreased to thirteen, and the correction of a second error brought the count down to two. Better yet, I've noticed in subText's generated output that the same error (a capitalized Title attribute, which is illegal in XHTML) is generated in a number of places, yet is only detected once by the validator. I can't fix that particular bug without recompiling subText, so it's staying broken.
