He probably shouldn't be using Medium to market his thing either. The signal-to-noise ratio is way too low. Unless the post really grabs my attention really quickly, I'm likely to close the tab. Custom-made, well designed, websites get a lot more of my patience.
Hey guys, sorry for the bother, we certainly don't want to abuse HN. All the posts had entirely different topics and we believe there are people who might genuinely benefit from them. If that's not the case, people won't upvote the posts and they will quickly fall into oblivion.
