When a blogger finds an interesting tidbit of news, he posts a link to it, along with a bit of commentary. Then other bloggers find that link and, if they agree it’s an interesting news item, post their own links pointing to it. This produces a cascade effect. Whatever the first blogger pointed toward can quickly amass so many links pointing in its direction that it rockets to worldwide notoriety in a matter of hours.
Sure sounds like they need MemeStreams.
