Thanks, Mike for your comment... I didn't mean on your post at all... :)
It was more about writing an ordinary blog post, and than BAM some pitch come from nowhere... lol...
Like @achim03 said in his comment, you (don't mean you directly... lol) have done an awesome post, and you devaluated it with some pitch at the end... There is no sense...
That's exactly what @jongolson preaching... push and pull... It's like people are scared that they will not have time to push, so they are using it EVERY time... or it's just a thought that they are wasting time if they don't SELL something... don't know...
