Pro users receiving banner ads? Answered
For a long while, the only ads I was seeing on Instructables pages were internal -- mostly examples of highly rated/featured I'bles, or contest announcements.
Starting today (24 Mar 2010), I am seeing banner and sidebar ads. This isn't a big deal, except that a lot of them have been those really annoying rollover-giant-box type. This makes it quite cumbersome to navigate on the page, and in particular, to do anything where your mouse has to go near the masthead.
