And here's a couple more folks with VSX/DSL related blog series that I missed from my previous post:

• Long-time DSL-er (and recent MSFT hire) Andre Furtado has a series of DSL posts indexed under DSL Tools: how to resources
• Sebastian Talamoni has a bunch of DSL posts including some funky property grid Verbs stuff
• Benjamin Schröter has a VSX/DSL series including a cool 3-parter on hacking up routing connections between line items in a collection.

It's really cool to see folks out there pushing our technology well beyond what comes out of the box.
