Enabling rich structure in weblogs

Syncato is a very interesting new peice of weblog software. Essentially, posts are XML fragments stored in an XML database, which can be powerfully and easily queried by users (Staken, via Udell).

One important consequence of this is that it provides strong motiviation to add metadata markup to your weblog posts, as then you can use the metadata in queries, to extract useful information from the weblog or to construct custom views of it, etc.
