I agree. This site seems to call-out anything with a certain kind of texture as "skeumorphic," and many of the examples are quite attractive on their own. But

I agree. This site seems to call-out anything with a certain kind of texture as "skeumorphic," and many of the examples are quite attractive on their own. But I think you're pigeonholing it into a certain school of design. I don't see it calling out just any texture -- only a certain range commonly found in software these days (especially on iOS). I'm talking about denim, paper, stone, leather, and other rough, durable surfaces that remind us of certain tactile sensations. (I'd also add a category for shiny, glossy, perhaps candy-like textures.) It certainly makes sense for these kinds of textures to appear most commonly on touch devices, but as designers it's good to understand when we're being a bit derivative. If anything, skeu.it will help me be more self-aware.
