RSS users don&#x27;t need ad blockers because obnoxious ads can&#x27;t come through in a (full-content) feed, but this means that feed users have all the downsides for the site as if they did have ad blockers.<p>And feed subscribers are much stickier than most web visitors - you can&#x27;t generally use a feed without subscribing to it, so anyone who uses a feed will see it again. The problem is that stickiness per se is not actually that valuable (especially when it&#x27;s difficult to quantify). Feed users are so sticky that they will read everything you post but never leave the site by clicking an ad.
