I've searched around a little but didn't find anything relavent:

Fairly recently, some of the ad placements have altered part of the page layout. First I thought it was my adblock just messing things up but that's not entirely the case. --Oh, and I know better than to block all ads on Neowin, just a few of the overly distracting ones.

Just curious if something changed other than my browser settings.

It's how I have the div for those items set up. It's floated, so sometimes content can end up behind it.

I noticed that the ads on the IPB main skin overlap on the bottom a little (I will add a screenshot shortly).
