Sorry about the multiple updates in the past couple of hours. I've migrated pbblog forward to a more recent version of SnipSnap. Among other things, referrers are back, thanks to SnipSnap's support for blacklisting. The update was trivial to perform by simply loading the dump from the old 0.4.2a installation, other than copying the files from the older installation and converting any inline entities (like """) in the snips to their UTF-8 equivalents.
