I've never seen much difference between the fonts. Some are a little easier on the eyes, but I usually just use the default font. I all looks pretty much the same to me. I look at what is actually being said. My brother-in-law does alot of graphic design stuff. I don't see much change from the begining to the end. I'm like, it still says pretty much the same thing. Maybe thats just me though. TV commercials are more likely to influence me to not buy something(like Old Navy) than they are to make me buy something. Maybe there is a correlation there, maybe not.
