I would think there might be a lot of problems with screen resolutions. Given that one's eyes need to be "relaxed" at a fixed position, that position might not correspond to the size of the image being viewed by different people. (I don't think I'm explaining myself well, LOL) Anyway, it might be harder to get a following on the internet because of that. I like stereograms and love looking at the poster versions, but they're usually too small on my computer to enjoy them in that format. So my "vote" is "whatever others want" but I personally probably won't be able to participate, LOL.
