Except you're forgetting that by focusing the topic it's a lot easier to contain the relevant information in a much smaller thread, where it's far easier to read through a handful of pages rather than hundreds, so less likely to have the same questions asked repeatedly. So, I doubt it would ever even approach a third of the front page. Nor am I suggesting that all the threads should be created at the same time, or even by the same person - just as required.
To make my point; I had a valid, core specific, query in my post a page back... has it been addressed? No. But my postscript about useful information getting lost in this two-hundred page behemoth has generated almost another whole page of off topic thread bloat.
