a blog called High Scalability
very obviously built with Drupal. funny, because scalability is a central topic of conversation when you get big/fancy Drupal developers together (thinking you can build the Next Big Thing with Drupal? --think again). because I wonder if they will talk about Drupal scalability at all. because Drupal itself is a bit of a resource hog, out of the box; the site at least *looks* straight out of the box.
