Emacs 24.1 is out. I haven't really tried it properly yet. All of the pre-release Emacs 24 snapshots I tried had severe memory-leak problems (at least with my set-up) and the quick try-out of 24.1 I did do revealed that it seems to be incompatible with twittering-mode. Since Emacs 23.3 is still working nicely for me, perhaps I'll wait a bit before trying 24.1 seriously.
Speaking of the future of Emacs, a great quote from sociologist Kieran Healy on The Setup ("usesthis.com") site:
Emacs ... will be there when the icecaps melt and the cities drown, when humanity destroys itself in fire and zombies, when the roaches finally achieve sentience, take over, and begin using computers themselves - at which point its various Ctrl-Meta key-chords will seem not merely satisfyingly ergonomic for the typical arthropod, but also direct evidence for the universe's Intelligent Design by some six-legged, multi-jointed God.
