It seems to me it's discussed as often as it is because it
is an issue that continues to annoy some of us. Perhaps because you don't have a problem accidentally turning pages you feel it's "over" discussed. What's your secret? Let us in on it, pls!

You've prolly posted elsewhere, but I missed it.
1. I read my Kindle in a cover (I have an Oberon but before this a M-edge and at the beginning, I used the original cover). Using a cover gives me a "ledge" for holding so it keeps my fingers out of the way of the page turning buttons.
2. Keep in mind that the keyboard is not active while reading, so I find that's a good place to put my thumbs and again, keep them out of the way of the page turning buttons.
3. I never, ever put my Kindle down without putting it to sleep (Alt-Aa). It takes a split second. From everything I have read (and this is only my anecdotal impressions, not empirical evidence) it seems that the accidental page turning happens when putting down/picking up the Kindle, not during reading.
For the first few days I owned my Kindle, I was very conscious of the page turning issue since I had read so many complaints. So I focused on training my mind/brain to do the above and now it is second nature. I don't even think about it anymore.
Showing my Kindle to someone else (since others tend to go willy nilly pushing buttons): I always put it down on a flat surface so we can look at it together. I demonstrate by pushing the buttons, then get into a document (usually the New York Times) and let them play around with navigation. They are not going to lose my place in the paper--especially one I read days ago.
That's what I do, hope there are a few hints that are useful for you!
