As it turns out, that is a theme that I have explored at length. I have a kitchen that is much too small and has, as a sort of ultimate poke in the eye, a blind corner, so I am much interested in what can be done to alleviate that particular problem. As a cabinetmaker, I can, and will, make pretty much whatever I want when we remodel our kitchen, but even though I can get these things much cheaper than the general public, if it doesn't make sense, I'm still not going to do it, no matter how slick it may look. And, frankly, that is the problem with the many "solutions" to blind corners. When you run the math on them, none of them really pencil out to much more storage space, and most of them actually provide less storage space. So, I do not recommend them.

That is, however, only for base cabinets. As you pointed out in your question, there are a number of solutions for the blind corner in wall cabinets that make all kinds of sense. The link at the bottom takes you to the one I like the best. And, if you're interested in the whole discussion on upper cabinets, it begins here:

Thanks!

Here is a pic of my upper corner cab. DH still needs to adjust the center of the door. It has a piano hinge in the center. Since it opens to empty space I do not worry about it hitting a cab next to it.
