I find Twitter is a bit different though, since it is not like putting your whole life up on a page, it can just be short catchups fairly regularly. Maybe it's better in this respect because it doesn't try to take the place of things like phone calls and email in the way Facebook does.
About the best example I can think of is the Atom publishing protocol where a service links to it's publishing URLs and a feed can provide pagination through hyperlinks. But still it is not a particularly sophisticated example, do you know of any others?
