@ Ted -- Appreciate the feedback on the ads! We are in the process of testing a new mobile ad system, so you may see different sizes and density of placements while we test and configure everything.
To share a bit of background, for the past 3-4 years we’ve made essentially nothing on the mobile site, with mobile ad revenue being less than 20¢ (yes, cents) per thousand pageviews. Earning less than a dollar for every five thousand times the blog is read obviously isn’t sustainable, and as more and more of our traffic shifts to mobile, we’re having to make adjustments.
We’re committed to finding a balance that doesn’t negatively impact the overall experience. Previously there were basically no ads on mobile (the majority of ads on the desktop site are in the sidebar, which on mobile doesn’t display until after all the content and all the comments, so was almost never viewed), so we know it's going to be an adjustment regardless. But you won’t see pop-up ads, auto-play videos, things that float and are hard to close, etc. — those types of ads are much more lucrative, but they’re also annoying.
So we’ll get this dialed-in, in a way that is hopefully not too obnoxious, and very much appreciate your patience and feedback in the meantime. Nothing has changed on the desktop site, if that helps.
