Oddly, technorati is updating its database with records from other sites(*), so the only thing I can conclude is that either Technorati doesn’t like this site or the WordPress/RPC/Ping Form/Pingomatic things aren’t working.

(*) Even a site which has no content and is updated once every blue moon has been indexed faster than this one – and it links here!
By the way – this seems to be a recurring theme:
