1st: This is only for developers, and i doubt that 99 percent of the MacRumors.com visitors are developers.
2nd: Many users use iOS devices to view MacRumors.com. Mavericks DP2 updates are useless for them.

Really wish there was a way to disable Top Sites. Its easily the most irritating 'feature' i've ever come across in almost a decade.
Um, set "New windows open with" and "New tabs open with" to "Empty Page"? If you do, you will never sit top sites unless you explicitly click on top sites button.

Very true, but this site's name is still MacRumors. Seems to me if they want to deprecate Mavericks and elevate iOS 7 that is there prerogative but for logic's sake they should also rename the site to iOSRumors.
