Content upkeep

I got tags working via a plugin. Since I was messing with the site anyway, I hacked together some Ruby code to pull all the content out of the database and perform automatic keyword extraction via naïve bayesian analysis. It spat out a file of SQL commands, consisting of the subject of each posting and the first line of text (in comments), followed by the commands to add the tags. I ran through the file in vim deleting here and adding there, then executed the result.
