The Wordie "W" is quite a bit different from the Wikipedia "W" because of a difference in font. Palatino Linotype is a pretty unique typestyle, in my mind different enough. I e-mailed you an image that is probably identical to the ones you tried. :-P But I think it's usable.
I hear you, but every 'W' variation I tried looked too much like the Wikipedia favicon. Not like they have a trademark on the letter 'W', but I'd rather avoid confusion and try to find something distinctive. I feel like the diacritic over the 'e' has a Wordie feel. As does doing things backasswards :-)
Much better, although I would suggest something that focuses on the "W" rather than the "E". There's an alliterative effect a favicon has at suggesting the name of the site it represents; the "ē" makes me think of web sites that start with that letter, like E*TRADE or eHarmony. :-)
I like it. Pretty awesome how recent comments have become the staple of the home page, and recent words have been relegated to a little sidebar. :-) It's a small difference, but really help to emphasize the social aspect of the site.
My only suggestion would be to revisit the Wordie favicon. I'm quite sure better is possible (no offense).
I agree, tiny little images might be helpful. And I'm working on my text-only issue, I really am. I was doing so before I even read your comment, actually: check this out. Small images! It's like the noosphere in action, right here on Wordie.
Okay, so here's a crazy idea. Those abbreviated names can be a little tricksy... and I know Wordie's sort of anti-images... but what if instead of text links we had little graphics? Like the favicons from each site? And the full name of each site in the ALT text? Additionally, there are a lot of times I'd like to do a regular Google search on a word, not a Google Definition search. Just some ideas... :-)
