This site has had both "Categories" and "Tags" since it was on Blogger in 2007. It occurs to me that this doesn't really make any sense, so I'm hiding the categories and won't be populating them going forward. The old category index pages are live (because cool URIs don't change) but otherwise, it's all tags from here on out.

A few other small changes:

• updated some CSS
• fixed missing </li> in page metadata block
• chnged post time to be a <time> so it's machine-parsable, and stopped displaying post time by default
• added signal and hackernews to the Social sidebar, and removed two defunct sites
• archive now shows tag information
