Everyone keeps telling the diagonal square looks like the Enron E when it's turned. So we better not do that. On #476 please "lay the square down and re-design the logo a bit so the i is upright." (I hope that makes sense).
I love #418 even more I think, though. I like the simplicity of it. Let's try a couple different fonts just to make sure we've got the right one. Take a look at #432. I really like the font used there. You also might try the grey used in #411.
Thank you!
