EveryBlock is indeed Mapnik rendering and thanks a lot for the compliment.
Chris, nice to know you appreciate Mapnik even if you wouldn't always "personally" recommend it ;) Building Mapnik usually doesn't pose a problem but if you're having trouble just give me a shout!
OpenLayers + TileCache + Mapnik and a bit of Shapely ;) We're working on improving our feeds and we'll have consumable geo data very soon. Thanks for checking us out.
