After seeing the new BlogTrack app and reading Paul’s comments on it, I wonder if services like this wouldn’t be better implemented with a “ping” interface. Instead of scanning and scraping for new content, weblog tools could simply send an “I’ve been updated!” message to interested aggregators. Weblogs.com requires this, as does the “Recently Updated” list at the Moveable Type site. It occurs to me that as weblogs gain ground as valuable information sources, there should be some interoperability between blogware and the tools that interface with it. Would aggregator tools benefit from a notification protocol? A MetaWeblogAggregator API? Does such a beast already exist? How about blogware that talks to each other?
