I’ve made exceptions a handful of times over the years, but as a general rule I refuse to link to anything on Facebook either, for the same reasons as Dave. Last week I linked to screenshots of a Facebook post to avoid linking to the original. The original post by Marc Haynes was public, which I know because I do not have a Facebook account, but here’s what it looks like for me without being a Facebook user — a full one-third of my window is covered by a pop-over trying to get me to sign in or sign up for Facebook. I will go out of my way to avoid linking to websites that are hostile to users with pop-overs. (For example, I’ve largely stopped linking to anything from Wired, because they have such an aggressive anti-ad-block detection scheme. Fuck them.)
