The OP leaves out two major subgroups: People who wear the shirt because they (or their friend / partner) is associated with the company, and folks who think the t-shirt is cool or nice. I don't wear t-shirts every day, but if I'm going to wear one, I'm not unlikely to choose a decent one that's loosely associated with something I worked on myself.

Lots of startup t-shirts suck, but there is occasionally one that's pretty nice and well-designed. (It helps if you have someone who knows what they're doing design it.)

But yeah, if you take some crappy bottom-dollar third-world t-shirt and stamp your logo on it 6" high, don't expect many people to wear it. And too many companies think that's a good idea.

Good call on the other groups. We're lucky enough to have @idangazit designing ours, so I believe they'll turn out alright =p
