This post is from one of several previous incarnations of this site and probably doesn’t quite fit the current format. In a former life this was a group blog and a tumblelog before it became a static jekyll site. If anything looks broken or is worded oddly that could be why. Pardon the dust.
Apparently “slug” is the preferred term for the hyphenated title in place of an ID in pretty urls. Who knew? Make it a lot easier to search for different implementation ideas though.
