When you enjoy something on Twitter, or when someone tweets at you and you want to politely acknowledge them as people but you don't care to engage, you grace that something with a "favorite." The "favorite" is represented by a yellow star.
That was the state of reality until 9AM ET this morning, when reality crumbled into a fractured heap of signs and symbols, all foreign, arbitrary, and deliberately indecipherable. Now when you enjoy something on Twitter, or when you are practicing social niceties on Twitter, you register those feelings with a "like." The "like" is represented by a pink heart.
Based on the cataclysmic reaction of the internet, no one understands why this happened. Although it might be for the very specific reason that Twitter says it happened: casual users of Twitter were confused by the term "favorite," and thought it was meant to be applied only to tweets that were actually their literal favorite.
All symbols are meaningless, and so are you
This concept made no sense because it would take an unfathomable amount of time to decide what tweet was your favorite in all the world of tweets. You would also have to constantly reevaluate your decision as more tweets entered the world and as, of course, the standards for great tweeting evolved over time. Leaving a tweet from 2009 as your favorite forever would be like calling Back to the Future your favorite movie forever — people would laugh at and perhaps be fearful of your total inability to understand the constant and beautiful advancing of the art form.
In this alternate version of the Twitter-verse, receiving a favorite would be about the most meaningful life experience one could hope for. But that's not the universe we live in — the universe of favorites, with their many interpretations. We live in the world of likes now, where there are just as many possible interpretations, all just as nebulous.
We are living in the Twitter multiverse
Anyway, all this to say: if you really feel like you must live in a different era than the one you actually live in, you can now install a Chrome extension called FavForever. The Chrome extension will make favorites and stars come back in some ways, but not all, as a reminder that the past is never as perfect as you think it was, you backwards-looking fool.
