I think it would be great if there was a section, solely for posting news about Win7, and the ongoing development regarding compatibility and features, sp's and so on. That way we could easely monitor it's progress along the way, and have a somewhat clear view on what changes over time regarding this exeptional OS. Maybe a subforum to this, or even just a sticky at the top ? Don't know, but I think it would be a great idea...
I reckon the notion of focus would be difficult... that topic will become enormous and full of unnescessary stuff.
Not if it's being maintained by someone, like the update centre... That way the unnessecary stuff would be filtered out, leaving the important stuff organized to the public view.
