Plus with the layout I could put more data on my tags if I ever wanted.

First, definitely read the discussion that someone else pointed to on your previous post (http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html). One thing it motivated me to do was dig into the other options of MySQL's fulltext searching. I obviously had read the docs very carefully because I totally missed the boolean search options (http://dev.mysql.com/doc/mysql/en/fulltext-boolean.html). Now that I know these options exist, I'm going to give fulltext searching another try as the performance problems of subqueries are starting to get me down. I just wanted to follow up a bit.
