(1) - depends. At this point in the update cycle, I'm guessing it's under 20%. From update -1 to update +3 it's more like 50/50.
(2) - Unless there are questions on the IQ test along the lines of, in a searchable forum of almost 20,000 posts over 10 months, what are the chances that your issue/topic hasn't already been substantively discussed?, I'd guess close to 50%. I think what we see in here is representative of society at large- a lack of perspective, arising from unchecked narcissism and ADD, drives the quality/content of the posts.
That said, when someone posts, I wanna fuck Jenat, the assumptions and data-gathering are easy.
