I need to vote 3 times! I'm a yes to position reading, and place holder for sure... contrast issue is dependent on the regular contrast it doesn't happen often but I do use it that way.
Now I'm a self-confessed habitual selector I feel compelled to say that in no way, shape or form do I select text like some kind of nervous tic. I rarely select text when reading HN comments for example, they're mostly short enough so I'm not going to have to scroll or have time to get pulled on to something else before finishing.
I voted for reading position because that's the one I use it for most.
