> I don't use ad blockers, due to my development work in web apps etc. I like my browsers to be as stock as possible, and I do actually at least glance at nearly all ads I see in FB etc. just to see how their targeting is being skewed by my search history or messaging online.

You are doing yourself a disservice. Have two users (or at least two browsers), one for work, which you keep ad-blocker free, and one for life, which you shouldn't.
