I've always wanted to add a commenting feature to my weblog (a custom hack that I call gemcast), but I've been too lazy to get around to it. That, and I just have an aversion to letting strangers write to my webserver's hard disk.

A hot tip from Vivian's site led me to HaloScan's commenting service. This allowed me to set up a commenting feature for my weblog in about five minutes. Really. Comment away, dear reader (the singular is quite appropriate).
