I really dislike rude posts or 'impolite' behaviour, that said, I really didn't see any of that in the OP. In fact, I was smiling when I read it, it has that typical 'tongue in cheek' style, at least, to me it does...and there is nothing wrong with that.
About the list.....I read some things I never thought of ( Occasionally I build houses and sell them on Marketplace ) and I will definitely take them to heart.
Kudos for starting this thread, Bastian.
