I think it's good to point out that DW is also not Google. Google still counts itself as being in Beta. There are many products that have beta up in the corner of the Google brand symbol.

Google finagles to be in beta for legal reasons, and as an easy excuse for stuff. We've all had gmail for what - 5 yrs now? And it's still Beta. Even though invite codes aren't needed anymore - people still earn them, they way they would in any other open Beta.

This is not what DW is doing. So it's yet another reason people shouldn't expect Beta to be without any problems what so ever.
