For his part, Meyer is quick to note that Facebook isn't the only one making gaffes like this. As he puts it, web designs seldom account for "worst-case scenarios" in people's lives. They frequently assume that you're sharing good news, or that you want to relive every memory. Developers aren't intentionally cruel, Meyer says, but they need to be aware that they could potentially exacerbate someone's suffering when they highlight content. Facebook is just learning that lesson the hard way.
