I contributed Versa examples to RDF Query and Rule languages Use Cases and Examples survey, announced just today, though only the first 3 examples I posted seem to have shown up so far. I think this site could be a good idea with some tweaks (especially giving better definitions of the RDF models being queried).

My Recipe: Merging XBEL Bookmark files has appeared in the Python Cookbook, though the note at the end with sample XBEL files for merging seems to have been corrupted in production. See the comment I added which addresses this.

Craeg Strong pointed me to Metacrap: Putting the torch to seven straw-men of the meta-utopia. It's a good hazing for folks in semantic/intelligent Web communities. Unfortunate that the author chooses the term "straw men" and thus makes it all too easy for detractors to knock him off the log, but I think some of these are points I've been trying to make for a while now. Sometimes an off-hand irreverend statement is worth loads of earnest advocacy. Points 2.1, 2.2 and 2.3 are the motivations of my article The Languages of the Semantic Web. Point 2.4, I think, is a dud: Any Intelligent Web must be a marketplace of ideas. Stupid people will simply lose, just as they do in today's Web. I've put points 2.5 and 2.7 into practice in projects involving ontologies. My motto in these has been: support diversity and disagreement, or fail. I didn't really follow point 2.6.

Speaking of my Sem Web article, looks like it got very kind words in a recent SearchDay issue.
