Switching to Haloscan

I got comment spammed last night in a big way (apparently it's possible for shitheads to automatically generate spam comments onto a blogpost, and I deleted about eight before I got really pissed off), so on a going-forward basis I'm switching to Haloscan for comments -- the link that will appear below any post will let you comment similarly to before. Hopefully that'll make the problem go away. If not, I'll try something else.
