I live on RSS. Any website that interests me, but doesn't have an RSS feed, I email the webmaster requesting one. There's no excuse anymore. If you take a look at my friends page, you'll see things like BoingBoing (a link blog), Something Positive (a web comic), Calvin and Hobbes, and so forth. These are all delivered via RSS, and you can add them to your friend's page through livejournal's syndication page- LJ provides an RSS aggregator for you. This I find preferable to downloading an RSS aggregator- a seperate program to read RSS subscriptions. Though, if I wanted to, I could use an aggregator and have my friend's page show up in it- LJ exports your journal and your friend's page in RSS.
RSS is what turned me into an infojunkie- all the glorious information I want, delivered to one place- and thanks to LJ, that one place is nicely styled, and mixed in with commentary and updates from people I know (or at least am interested by).
It is the Nexus! Bwhahahaha!
