I do agree with you that ads on the interfaces we are using are a bad business move. The ads Im mentioning though are for our own articles. Not the interfaces we are using. They will hopefully and most likely always stay clean.
As for @dclick, it just gives you an option to integrate a banner with a link at the bottom of your article.
See how it looks at the end of the post about it. There is nothing negative about it if you ask me.
