So far we haven't noticed any impact in traffic from the use of high-impact ads, but that's definitely something that we'll be monitoring. In regards to content overlap, the high-impact banner ads push the page down, but it doesn't overlap the content. If it does, that's a bug with the ad. If you see an actual content overlap then that's definitely something you can let us know about.
