Thank you for your insightful replies! Automated suggestions for categories and generation of 'See also' & soft links sound like very useful applications of the observed community structure of Wikipedia. I'll study these issues in more detail.
Thank you for your assistance! Dmitry
Sounds like it could be used as an automated 'See also' generator - one could write a bot that for each article, generates a list of 'top 10 related links', check to see whether they are all in the article already, and add any missing ones into the See also section (or create a new one).
Even more work would be on-the-fly generation of related links - so it'd be akin to Everything2's soft links (a feature I miss dearly)
