I don't quite understand your complaint.
A decent search usually turns up the "personal opinion" or "preferences" many have already written -- over and over and over and over and over again, on popular and generally unchanging topics like this -- so the OP's results would be the same.
Might be different if the query is about some kind of new/emerging technology or maybe a topic that's in flux for some other reason... but generally discussions about the pros and cons of singles/twins, anchors, and a few others, probably aren't gonna surface much if any new factoids, opinions, preferences... Somebody might say something in a different way than they've said it 30 times previously, and the different wording could perhaps be useful... but that's kind of a reach.
"Decent search" usually means using the Google or at least the Advanced versions, given the site's base search tool isn't great. And many new users don't know the base tool is so limited, so they don't always find much if that's the only tool they've tried...
Anyway, what do you see as the advantage of asking a commonly-asked question all over again? FWIW, I don't see it as a bad thing, just usually slow for my own purposes...
