hCard profile import is erratic

I've tested the hCard profile importer (http://getsatisfaction.com/people/new) and had mixed results. Last.fm imports in particular seem to be hit-and-miss (sometimes it finds the profile, sometimes not); my Technorati profile will not import at all ("This profile does not support hCard"). Flickr seems to work reliably.
The reason it came up is I'm trying to verify it against Rosebleed's user profiles (eg. http://rosebleed.net/users/profile.ph...) and having no luck. I suspect part of the problem may be the hCard+XFN friends list, but even on a profile with no friends list it doesn't work. (I seem to recall that it has worked in the past, but can't reproduce it now)
 
sad I’m frustrated
