HackerSluts, the feed concentrator for sex and relationship blogs. I've even put a neat little "suggest a feed" form on the front page and everything. :)
It's still not 100% finished, though it seems that Web projects seldom are. I do at some point want to turn it into a fully multiuser system (so that people can create their own unique logins, arrange feeds the way they'd like to see them, and have the system store their preferences and keep track of their read and unread feeds), but the basic aggregator package I'm using isn't set up for that, so it'd likely take some pretty major coding. Eventually I'll also make the display of the unread feeds prettier and more flexible.
But hey, if anyone out there knows someone who might be interested, or who has a feed they might like to submit, spread the word!
