I do a lot of aerodynamic research and testing, and post the content over on my Occam's Racer website. I hate ads and popups, and so there aren't any. I don't sell anything, either. I'm not swayed by manufacturers because I buy everything at retail price. In the end, it costs me money to create the content and host the site. Why I'm still doing this is beyond me, but if you enjoy the content and would like more of it, buy me a coffee!
I'm a technical writer, and we often joke about "coffee in, software out." But for realz, I drink a lot of coffee and it's accurate to say my site is fueled by it.
