We've long since moved off of that home-grown app to the robust and integrated mydW platform. That's three blog applications (we used Roller for a number of years), four servers, four databases, innumerable infrastructure upgrades, bug fixes, new features etc. etc. I'm proud that through it all we retained all of our entries, comments, and links (our original links still work, it drives me crazy when other sites don't maintain links).
Check out dW Editor-in-Chief Michael O'Connell's first dW blog post five and a half years ago about the mission of our community with a message that still resonates today.
Poor Michael didn't even get a comment on that first post, maybe he'll get one now :)
