Yes and no. They're pretty bleeding-edge in terms of system features. In terms of UI, they tend to want lots of terminals and not a lot else.
Which is completely fine: I do too. But I'm not GNOME 3's target market. David Miller was talking about running awesome, which is much better suited to terminals and vim.
You can't be all things to all people. GNOME 2 tried and the result was very underwhelming for everyone. GNOME 3 is more polarising: the kinds of people who comment on LWN don't all love it. But it's infinitely more appealing to the kinds of people who actually statistically exist.
