So far my favorite is the one currently at the top of the forums.
There's a reason I put logos in the forum header. It means that's my favorite choice, and it becomes the de facto benchmark for other logo attempts.
Is there a reason, other than ascetics, for the "w" not being capitalized?
Nope. Just the aesthetics.
I'm kind of silly that way, proper nouns that are in small caps kind of make my ass twitch.
A capital W with that font would make it twitch even more.
Makes me wish I had experience with graphic design and the assorted programs for making art and logos. :)
You don't need to have experience -- I'm the living example of that, I never touched vector programs before this week. (I did use 3DS Max and Blender but (1) they're 3D, (2) I sucked HARD at them and needed them at work so let's not remind me of that too much :P
What you need is a sense of taste that reconciles everyone's ;)
