As you may have noticed, I have changed TWiT.tv into a read-only web site, without logins and commenting (much as Alex has done at pixelcorps.tv).
It's not that I don't welcome your comments, but I'm having all sorts of difficulties with the software over cookies and log-ins. Add to that the difficulty of moderating thousands of entries for spam, and I think you'll see that it's impractical for now to keep things as they are. At some point I hope to find a Drupal developer I can afford (Lullabot is way beyond my means these days) and I'll be able to update this site to Drupal 5 and restore some of the interactivity. Until then we'll have to live with a simpler design.
