Facebook recognizes this, and one of its engineers, Dan Muriello, recently revealed that the company has experimented with a "Sympathize" button for these nebulous circumstances where you want to express interest without suggesting outright approval or enthusiasm. According to the Huffington Post, some Facebook engineers dreamed up a "Sympathize" button at a hackathon held not long ago.
Though "out-of-the-box" ideas often emerge at these types of events, few of them every materialize on the social network. What's important, however, is that the site's engineers are aware of how restricting their current language can be. "Some of our best ideas come from hackathons," a Facebook spokesperson told the Huffington Post, "and the many ideas that don’t get pursued often help us think differently about how we can improve our service." Even the "Like" button itself emerged from one such hackathon. So, news hounds, have hope. (Huffington Post)
