I've heard that your hourly comment limit goes away after a certain amount of time on the site, but mine hasn't, and I've been on the site for 2 years now. At what point can I post >4 comments/hour?

When you get an upgraded account.

best way to achieve that might be to take on some tagging projects or write some wiki pages or something :D
