"For the record, I had the same reaction to OPML. I still don't get that XML either. Do we need OPML *and* MSFT Simple List Extension? Do we need either? I am unconvinced." -Patrick Logan I am very much enjoying Patrick's blog, syndicated as it is, using a simple XML format. So simple that once people thought it was pretty pointless, even for syndication and sitemaps. Today it's on the verge of becoming the lingua franca for everthing from searches to shopping to web services. Lists are next. There is so much web data in ordered lists, it's not funny. An XML format for lists, however trivial, is going to have a massive impact. We could even end up with 2 or 3 different list formats and it would still have a massive impact. If it seems trivial beyond belief... well I guess there's no denying that, but it's exactly the absence of barriers to entry that make stuff like Atom/RSS and List markups cool....
