Well, where are we now..?
I'm suggesting that the bulk of English speakers in the world, especially in the realm of internet users, don't speak German and French as well.
So would it be too great a leap to help those English speakers by restricting results to those written in English? (This isn't a big ask, it seems to me. Discriminating by language to language.) Hell, these are computers: make it settable in Profile.
As for a forum poll - it's a bit like pirated software: flawed logic: Would all those who use pirated software have bought the product if it hadn't been available piratedly? Similarly, a poll here is addressed by only those who visit the site, those who DO like the way it works or those who are prepared to tolerate it. Those who the forum has driven away wouldn't, of course, vote.
Managerial perspective demands decisions in states of uncertainty.
