I suppose in fairness the launch of Windows 8 is a fairly significant event, so a single thread might be a bit unrealistic. If people have a *specific* question or issue, insisting that they tack it onto a single humonguous thread where many things are being discussed simultanously might not be the most effective way to help them or anyone else having a similar problem.
I agree though that there's no need for multiple generic "is-it-any-good" type threads all repeating the same stuff over and over and over and over....
edit: just saw bledd's post about a dedicated subforum, seems the obvious way to go...
