Here are my current thoughts.
Old logo
-- Like duck part; don't want to change it.
-- Century Gothic (old font) was at one point pervasive throughout the site, but now this is its only place left, so it could use an upgrade.
-- Like how it maintains some professionalism with the logo. I actually get a lot of complaints the site is too childish, and this really helps it I think. In case you never saw it, this was the old old logo.
New Green
--Don't see much difference on my laptop (can tell more on my desktop w/ big monitors).
--Agree that if it is bolder, lighter makes more sense.
--So good with this change.
Font
--Would like to see some mockups with those other fonts.
--The Futura one looks pretty good, but is too stretched vertically.
--Like the curvature on the 20th cen. but agree there is something less clear about it.
--Like the bubble font, but think it is too childish given we're already pigeonholed in that area.
Red text
--Think by itself it looks pretty good, but with the logo it seems too much and takes away some of the professionalism. Still prefer black.
