The site logo is something that can be added to the header, other than the header image? But, I don't have anything to use as a logo. Nice option but more like an extra toy to either play with or spend money on. Luckily it's just an added frill so I can skip it until I actually figure out how to make a logo that isn't too hopeless.

At first seeing this logo post I thought it was a way for theme developers to add their logo to any sites using the theme. I wonder how many others will be confused in the same way.
