Wow. Talk about parroting a misunderstood argument.
Websites are not "the cloud". "The cloud" Apple sucks at is a different cloud to what you seem to think "the cloud" is.
This, most definitively, is *not* a sign that Apple sucks at "The Cloud" or even at its own cloud.
Stop parroting arguments heard elsewhere, they have the opposite effect and just get diluted and become little more than bland memes.
"The Cloud" apple "sucks" at is related to services and APIs for online functionality. You might want to stretch the concept of "The Cloud" pointlessly to include things like Ping or MobileMe/iTools (although you'd start showing not understanding what "the cloud" is supposed to be).
Most definitively, a big part of iCloud, for example, sucks balls.
But bringing down web pages for maintenance (regardless of how well/bad it goes) is a design decision, not Apple sucking at "the cloud". That the different Stores still use WebObjects is a design decision and, within its idiosincrasies, it works OK (I'd change it, but because I like modern systems and methodologies, not because they "suck", although a BIG part of Apple's marketing is now bringing down the stores and they'd keep doing it -and it would be OK- even if they didn't need to).
