I just finished XHTML validating the site. Now for the RSS feeds. Maybe Technorati will finally start looking at my site.
Check it out: W3C Markup Validator
Edit:Victory is mine! My entries are now starting to show up in Technorati! Huzzah! huzzah! Huzzah! I looks like after the clean up, the Technorati spiders were finally able to work with the site. Sadly, it took me having to remove my Amazon links to do it. (Drat!) However, I think I know how to get around that. (See the post More on Technorati Problems for more information.)
