While not everybody likes Phoronix (common complaints include tabloid journalism), they are doing a GNOME user survey again this year. If you are concerned about Linux on the desktop, you might want to participate; it is not particularly long.

Unfortunately, “the GNOME Foundation still isn’t interested in having a user survey”, and may again ignore the results; and already last year you could see a lot of articles along the lines of The Survey That GNOME Would Rather Ignore. One more reason to fill it out.
