I have always admired your diligence and attention to detail, but 519 forums?
Actually more and I've yet to fully investigate the blog access versus forum access at the two blog sites Impulsedriven and JoeUser.
The thing is that there is a *lot* of forum sharing going on and actually has always been going on. I'm not entirely sure what the difference is now but there most definitely is a difference. It's probably a combination of many factors.
In any case as an engineer the only way that I find that I can understand something is to take it apart and see if I can put it together again. But it really is quite confusing, the exceptions far outnumber the rules. But in the end I hope to simply *know* that when I post to such and such a forum then that appears on this and that site.
The other thing is the importance of any particular forum can be very deceiving. Personal Computing for example. On some sites it's a top level category with many sub and sub-sub categories under it (47 on Joe User) whereas on GalCiv2 it's merely a sub-forum of Off-topic. On Wincustomize it gains significant import as well. Posting something frivolous in the forum may seem prefectly fine on GalCiv2 yet risk the ire of a lot of folks on WC.
I just need to know and understand my environment. An exhaustive map of stardocks forums over it's 11 sites is tedious work but far less tedious than mid-game of a gigantic all abundant. I'll have something to publish probably within a week.
