Original arch - Wendy said she thought it was a little rainbowish. I see that. I liked the "building" story - arch and creative but I think that also works with some of the ones below too...
Solid colored arch - horiztonal
Horizontal logo with arch going w (web?) to t (not sure what that one means)? Could play with this if we like idea. Also might want to try a different "w" font? :-)
Stacked options with solid arches intertwined, gradient arches and then some playing with the colors.
OK, here's the original, alternative font treatments - just looking at some possibilities. click here
