Yes and no for me. I can't stand the stuff myself in my own dwellings (got enough of it when I was a kid) and they have almost gone the way of the dodo bird in where I live. The chiq thing today are either parket flooring; fake and real or just ordinary floors like linoleums. If I encounter carpets nowadays its usually only in apartments and housings where the elderly live or in the communal area in apartment housings like the stairwells or at work places (offices and such) and institutions (hospitals and nursery homes).
I'm afraid I find I have the same attitude when it comes to my decoration in game. I use carpets very sparingly and very rarely corner to corner. I find carpets useful when creating rugs that have to be bigger than the traditional ones found ingame. I have downloaded a few user created carpets though.
