OK, so we have analysed about a third of the thread now. The largest complete section runs from 1 to 3000 (posts), so I will now post statistics on
these posts only.
Just a brief word on methodology - each post has been categorised as either an incorrect guess, correct guess, picture, response from poster of this picture, or other. This is not an exact science, but we have done our best. I should point out, for instance, that whilst we have 270 "pictures" in this region, only 253 seem to have confirmed answers.
Please remember that we're only human. A lot of what happens on this thread is too complicated to analyse simply, so take this all with a certain pinch of salt.

We have made astonishing progress on the census, but volunteers are still needed, mainly to stop paulravuslante from going braindead (he has done at least 1300 of the post analysis)!
