New DrupalSites is up
Drupal 7 upgrade took a week longer than expected, but the result is quite nice. Shiny, trendy new design (not quite finished yet though), larger screenshots as many requested, better category list, and indeed an easier feature upgrades for future.
Our busy screen-shooting robot revisited all listed urls again, so if you had your own screenshot attached, now it was replaced by a new one. And it is not that bad actually, as now we have a very recent (current) screenshots for all the sites (before that many would have some few years old ones).
The process of creating screenshots also allowed to clean up the listings. It was much easier to spot dead or not-drupal-anymore sites visually. We cleaned up around 1k wrong entries. So the total listings count dropped quite a bit, but the quality level has rocketed.
On the pity side: due to CKK file field upgrade bug (http://drupal.org/node/1558192) we had to remove all submitted user pictures. But turned out there were not that many as majority of users are happy with their gravatars.
