I found a link to a blog post which reads:
"The T-shirt rule. It's a simple test of whether you've created a remarkable experience: Would I buy the t-shirt?
A t-shirt for your blog or your accounting firm or your bug-fighting software. If you're not t-shirt worthy, what would it take?"
Since I don't think anybody would wear a "The Other Drummer" t-shirt, let alone pay for one, I will ask you my (five) loyal readers: what would it take make this blog t-shirt worthy?
