Overuse (and misuse) of the word “like” is an obstacle to clear speaking and clear thinking. It is also a signal to the rest of the world that one need not be taken seriously.
Christopher Hitchens has an amusing article on the history of “like,” pointing out that “in some cases the term has become simultaneously a crutch and a tic, driving out the rest of the vocabulary as candy expels vegetables. But it didn’t start off that way, and might possibly be worth saving in a modified form.”
I largely agree. Read the whole thing over at Vanity Fair.
