I'm working on a new website and, as part of that process, I'm moving things around. The existing version of the site (that you are presumably trying to visit right now) is now available at legacy.29thfloor.com and will continue to be available after the new site launches (for some reason).
The new site will be very much a work in progress. I'm basically going to be building and evolving the site and documenting the progress. I don't know if anyone else will be interested, but I'm looking forward to it.
