The current implementation of [[Special:Random]],
however, gives equal weight to every existing article and
this is perceived as a problem that needs to be fixed.
We talked about this on
Wikimania.
If you compare our current implementation to wheel of fortune [1]; all
our articles are evenly spread around.
Weighted would be putting bot articles closer to each other so you would
hit them less often. You just need a good algorithm to calculate this
distribution.
You could implement this algorithm as an extension in MediaWiki that
updates page_random with this different distribution. This way you don't
need to update the database schema, just the logic at the page save.
