My biggest complaint with ads is when I open a site on my tablet, get two paragraphs into the article and then the ads start reloading/resizing/fucking-with-the-site and I have to scroll all around to find my spot and continue reading.
Especially annoying is the newer thing where again I start reading and the “click to continue reading” crap loads and obscures the last half of the paragraph I just read.
Is it me or is that just some kind of overlay on the full page that already loaded?
