Based on ~stevenf's post RSS to Web, I've finally gotten around to building a page of the feeds I read daily.
In the comments section of his post, to which I've posted, I found a link to Feed on Feeds, a fully-featured php/mysql aggregator application. In fact, it was so fully-featured, I wasn't comfortable using it for a public feeds page!
However, I was also able to find in his comments a link to Magpie RSS, a php-rss parser. With it and Feed on Feeds, I was able to hack together a rudimentary page to be updated hourly by cron.
Not too shabby for half a day's work, though I'm just told by Brent that the CSS isn't rendering properly in IE. Now there's a surprise. Gah.
Update: IE now renders it decently, at the expense of the other browsers - but the compromise was minimal. Also; I'd be remiss to not mention the other inspiration for the site, and that's Brendyn Alexander's RSS roll for the #joiito IRC channel.
