I don't want my whole LiveJournal on my website; I want to use tags to generate multiple feeds and pull in a feed of posts about my writing, a feed of posts about my travels and so on. Rummaging in lj_nifty produced this service for producing an RSS feed for one of your LJ tags which does almost exactly what I want. (It would be very nice if the service went into the LJ code proper, because kind as it is of avatraxiom to host it, LJ will have better availability long term.) The LJ RSS only delivers recent posts and if there aren't any posts with your tag in the most recent batch you won't get any posts for that tag. RSS isn't all about what's new and shiny, LJ!
