The current favicon is a bit vague: a speech bubble containing the letters "EM".
It's okay once you know what it is, but it doesn't really suggest "Emacs" to me.
(No offense intended to whoever made it -- it's not an easy format to work with. Although I see now that it's a pretty common look for sites on the network, so I guess it wasn't designed for this site as such.)
Do we want to change it? Does anyone have a better idea which would work in a 16x16 pixel format?
Speech bubbles are clearly a theme, but a few sites have made them their own. Perhaps stylised parentheses would make an appropriate bubble for us?
I tried to make "M-x" work in a bubble, but I don't think there's enough space for that. Perhaps just a question mark would be better, if the rest of the icon was distinctive.
My rubbish gimp skills could only manage this as a general impression of what I was thinking:
I'm sure it could look a whole lot better than that, though.
Perhaps a better idea would be the sequence
C-h (with no bubble) ?
