WordPress bug?
My rss feeds were not validating for some reason. I could see the file from a browser, but using any rss reader or feedvalidator.org gave a 404 error file not found. However, when I looked at the actual apache log files it was showing a normal 200. After digging around I eventually found this on the wordpress support forums. I changed the permalink structure to /%year%/%monthnum%/%postnum%/ , this also changed the rss feed mod_rewrite rules to be under blog/feed/ and now everything works properly. Hopefully.
