My first impression of the Tee logo resembles a rest room sign (sorry). Just a thought, since "Swell Info" is already Branded with an awesome recognized Logo. When you already have a Brand Logo that's identifiable sometimes moving on to other unfamiliar logo's not necessary. If the Tee had the Swell Info Logo on top, Swell Info.Com under it and "It's all Swell" under that reinforces already established marketing strategies of the web site, kinda like if it ain't broke don't fix it.
We've sold some where around 250 green man tees... I made a basic Swellinfo logo tee shirt, and it took about 2 years to get rid of them... So, the majority of people seem to like the green man tee. It is kind of an inside deal... Its the warm fuzzy feeling the double overhead green man gives you
