As you might have noticed, the original source of Web-Of-Trust Graph information went offline and probably won't come back. As a result also pathfinders like the one of Henk P. Penning are stuck in February 2012.
As I always found this kind of statistics interesting I've hacked the pks2wot python script that is part of the wotsap package to use normal hkp instead of the pks client and running it against my own sks keyserver which seems to work good enough to do a weekly dump of the current web-of-trust which can be found at http://wot.christoph-egger.org/download/. I'd be happy to hear if this is useful to anyone besides myself.
