It probably isn't a big deal (considering basically nothing uses it), but it appears google isn't catching on to the base path in regards to microdata. See here: http://www.google.com/webmasters/to...http://www.team9000.net/members/wootalyzer.1/ It's treating the paths in microdata as relative from the current page. I don't know anything about the microdata standard, so I'm not sure if it's supposed to respect the page's base tag or not. The links may need to be absolute. -- whoops, this probably should have been a bug report.
