News flash: coupons are still boring and I don’t want to give out my email address to a service I don’t even know I’ll benefit from. So now we have an App Store that serves nothing but candy, and we all love candy don’t we?
The OP is not the intended audience for most/all of the apps he's talking about. I don't think he understands that.
There are apps and companies that seem to be absolutely superfluous -- how many Groupon clones do we need? (Do we even really need Groupon?)
But the market will decide that. Not us nerds.
