Help Optimize Avitar.Net Systems Administration Site

Hey all,

I have been working on optimizing my personal site (Avitar.Net) that mainly has a bunch of articles on web development and system administration.

I am worried that the site may be overoptimized or hard for search engines to read. Googlebot is due back to my site any day now so I want to get finishing touches done so I don't get sandboxed.

Any critique any aspect of the web site is appreciated.

Currently I run the site through a killer architechture that is completely xml/database driven with only a couple perl apps that interface the database. (yes even the templates are in the database). So I wrote a script to generate my keywords & meta tags automatically based on a pages content... Does it look ok, or do I need to work on it somewhere.
