I cannot believe that the president just exhorted us to overhaul our immigration system on the basis of, err, Instagram. Oh, where would the economy be without this “online photo-sharing and social networking service that enables its users to take a picture, apply a digital filter to it, and share it on a variety of social networking services, including its own and other leading sites such as Facebook or Twitter”?
Also: “a student. . . their idea”; singular noun, plural possessive adjective? Reminds me of his “enormity” howler back in November.
