Jake – LJ does offer RSS feeds for everyone, though they only offer partial text feeds for free users. Your feed would be here:

Also, if you edit your userinfo page in LJ, it gives you an option to ping weblogs.com automatically whenever you update, and weblogs.com also pings blogrolling.com. While the process isn’t glitch-free–for example, the ping goes through even when I post to a community, when there’s no new post in my actual journal–it does make things a little easier.
