Nice to see this thread about WordPress here at WebmasterWorld.

These are the same sorts of issues that I have been banging on about with forums, such as vBulletin, for the last year or two.

If you herd the bot into indexing what you want to be indexed and restrict all the alternative URLs you will not see any Supplemental Results for your site.

If you are already indexed, it will take a year for the supplemental results to fade out, but you will notice other improvements within a month or so of making the changes.
