Parallax effect advertising

I think we should add Parallax advertising effect while scrolling the timeline messages. It has many advantages and users don't feel them as much annoying as other types of advertising... the UI stays nice, ads don't keep staring at you all the time...and users can scroll past them or come back till they are not changed or expired... What do you guys think about it? Should we have them on timeline? I don't think any other social website have it yet.
