The story on why there is the link-to-me module on the bottom of the profile page: I was thinking about a problem with OpenID accounts (on the one hand: the internal "ext_#" username needed to be exposed less; on the other hand, people still needed to be able to know the "ext_#" username for OpenID users to link to them and such), and I got fed up of doing that, and fucked off to YouTube to procrastinate. Where YouTube's lovely copy-this-code-to-embed-or-link jumped out at me, and I ran screeching back to Bugzilla with the problem answered and the video forgotten.
