I have a favorite food. My favorite food is sweet potatoes. The preparation is almost entirely meaningless to me. If there is a sweet potato in it, I probably like it because sweet potatoes are my favorite. On Twitter, you can favorite a tweet. Every tweet I favorite is not my favorite tweet ever tweeted. How can I have a favorite food, the superlative sweet potato, and have thousands of favorited tweets, none of which is superlative in any demonstrable way?
The Message talks about the different meanings of the ‘favorite’ on Twitter, as well as a bit about the uproar that went around when the star icon was (briefly) changed to a heart on the Android app.
