Thanks! Full disclosure -- it is my first advertisement, ever, so I'm glad you liked it :)
I would challenge the assumption that this is purely advertisement, though. In my head, this is not "buy our shit™" type of post -- in fact, there's no mention of buying the subscription anywhere. All there is is a link to a demo, with a valid challenge (not a fizzbuzz/fibonacci, but one you can actually have a lot of fun with), which we provide for free to anyone, w/o even requiring valid email -- it is up to you if you don't wanna reset the password later. Instead, the post is more of a "use the right metric -- here's our experience and what has worked for us" type of post.
Would you agree that this is a more fair assessment?
As of 2 Aug, can’t read your ad. Your cert expired today.
By the time I got to the end, I realized it was an advertisement, but still felt I had learned something useful.
