  • Popular videos and articles get reposted or discussed on dozens or hundreds of sites. But Web experts are now thinking about how to keep track of online conversation in real time, even when it's scattered all over the Web. A new crop of protocols aim to do just that.
    The protocols provide notifications when new content is available, rather than passively waiting for search crawlers or feed readers to discover the content. For example, pubsubhubbub, an extension to the protocols used today to syndicate content, can push content out to feed readers as it's updated. Building on that Salmon, a protocol first proposed last month, could allow comments to "swim upstream" to connect to the original post, regardless of where they're made.
