wgetutility on your machine (available on many unix distros, downloadable for Mac OS X, maybe even for windows), you could quickly do a poor man's backup:
That should suck down your comments index and every page referenced off of it.
wget --recursive --level=2 http://www.metafilter.com/search_comments.cfm?user_ID=<your user id here>
How about a feature to export all of your own comments, akin to Movable Type's 'export blog' feature? Something that's accessible only from your 'Customize' page, perhaps, which would prevent people using it as some kind of RSS feed and hammering the server (for the same reason, provided as a plain text file with only a few fields - time/date, permalink, entry - rather than some kind of XML). Perhaps with a check-box to choose (a) MeFi or (b) MeTa comments, and the ability to set a particular date or thread number as the starting point, so that you're not always exporting from day one.
This might sound like more load on the server, but it could instead save on server-load, as those who don't care about archiving wouldn't use it (and if it sits on the Customize page it would be out of sight, out of mind for most), while those who do want to archive would no longer be pulling up dozens of full pages to do it.
I'm not suggesting some sort of universal tool that would let you export comments by other users (as that could conceivably be used for Evil, yes, eeevil); just your own.
