Two suggestions regarding the new links:
Just now I wanted to hand out a link to an old question of mine, so I went to my user profile and found it in my question list. However, in order to get the link tagged with my user id, I had to actually click through to the question and find the 'link' href. Could user profiles use the new link instead of the older one?
Could the question title (the arbitrary verbiage that follows the question id) be included in the user-tagged links? It is very helpful for readers to identify the content it contains, and would increase clickthroughs in environments where bare URLs are all that are seen (e.g. IRC channels).
