While I'm thinking about it (and surely this must have been proposed
before and I'm not using the correct search term), some incentive to
decorate user pages could be curbed by not indexing it in the search
engines. That is, add nofollow to the html in User and User talk.
I'm actually a bit disgruntled that Google places such a high priority on
Wikipedia that my (fairly sparse) User page recently became the top entry,
rather than the more useful entries about my security work. So, for
professionals, nofollow would be a boon.
Pointers to code would be appreciated.
