I might have already complained about this. I'm getting old and I can't remember all my jimmie rustles from day to day.
I look through Facebook and mostly don't comment or like, because it isn't worth the fucking hassle half the time. But every once in awhile something makes me laugh, and I start to Worf it...only to realize that I can't. I guess Facebook doesn't have the kind of granularity that we do.
And before you say it, no, the laughing face isn't the same as a Worf! A Worf can be used sarcastically or ironically or even misleadingly, but a laughing face can't. When you post that your essential oils helped cure your kid's cold, if I laugh, I'm a dick. If I had a Worf though, it would be more subtle and I could probably slip it past because the whore (because you know a female posted that) might think I'm giving a guffaw of approval. Even though I'm not.
In short, amod please implement all of our reactions for use on Facebook.
