There's nothing being sold, and I will make no money. So not sure calling it an ad is fair. I am definitely an advocate though. I was recommended to try out stacker news, and I'll probably keep using it based on the immediate success. I write about lots of stuff, usually explainers and guides for 'beginners' of various bitcoin topics. Keep an eye out, I will be writing more about potential outcomes of forks, and other scaling matters.
