I think you forgot brand ambassadors, people who actually wear your shirt because they love your service, want to promote it, and proudly do so. These ones are the best, because when asked what the company is or does, they'll know what to say and enthusiastically do so. I know bands who wear our shirts and absolutely tell people what Earbits is when asked, which you don't get from someone who says - I don't know, I just got this free shirt at a conference.

Exactly. You need to shower the right people with t-shirts. It's no different than any other form of marketing - you have to have a plan. You have to know who to target. When done right, targeting your ambassadors and showering them with gifts of swag can really boost your marketing.

This is what happens with the Appharbor t-shirt I won in a contest a while back. People ask what the logo means and I explain, if it's a developer I get a bit more in-depth in how awesome it is.

I do this with my favourite T-shirts.

Also, they're simply better quality than the T-shirts I've bought myself.
