Yes Camp, I'm very sure I know about usability. My SEO Blog lol, well let's say that makes me no money because I don't use it for generating revenue and just something to post my thoughts on. That's the very least of my priorities lol.
Therefore I'm not particularly interested in the usability aspect of my blog. I post, people read. I'm not selling anything nor trying to make money.
I have spent literally hundreds of hours on usability testing on my e-commerce sites, the ones that make me money, the ones that I care about.
