I've always been puzzled at the extreme conservatism of many desktop Linux users. Back in the beta days of Gnome 2, I remember reading on Slashdot how anti-aliased fonts were sure to be slow and blurry and yet another symptom of the dumbing down of Linux desktops. Nowadays, you never hear anyone clamouring for a return to non-aliased fonts—I guess all those folks are now busy complaining about needing an extra key-press to access the "Shutdown" menu item.
The experimentation in desktop Linux makes now an exciting time. This doesn't mean I'm always 100% down with every decision Gnome takes, but I'm interested to see where things go. Props as well to all the other innovators, like Unity and KDE4, and also to the MATÉ project for actually stepping up and maintaining the desktop they want instead of just whining about things.
