You may have heard it all, but what SO has chiefly achieved IMO is to drive users who regularly answer questions away from the site. If you've a moment to check the data, I'd be curious to see the % of users who answer 5x more questions than they ask, and the same for 10x, 25x, 50x, and 100x. Then look at what their respective activity is in terms of answers provided over time per individual and overall. I'd be surprised if these numbers haven't each dropped significantly in the past 5 years, except perhaps the overall/total activity of high answer:question ratio (but then I'd expect the answer:question ratio to have materially dropped).
