     Compared to this litany, the 2010s look a little uneventful, don’t they? Even if you declare Obamacare a big [expletive] deal and grant Trump’s election world-historical significance, even if you bring in European dramas like Brexit and the Syrian refugee crisis, even if you pretend self-driving cars are really happening (just as soon as they learn to drive in rain …) … even then, the last decade’s disruptions don’t quite measure up.

     [Chappell] Roan draws from the mega-pop of the 2010s, from Lady Gaga to Taylor Swift – then laces it with sexually frank asides and lavish doses of camp, and performs it with a maximalist, absurd aesthetic indebted to drag, John Waters and Freddie Mercury.

• Once the 2000s ended, some people went back to the old pre-2000 formula of pronouncing years, leading to the pronunciations "twenty ten", "twenty eleven", "twenty twelve" etc. Others, however, continued the new post-1999 formula of pronouncing years, leading to the pronunciations "two thousand ten", "two thousand eleven", "two thousand twelve" etc. Both pronunciations are used, but the "twenty ten" pronunciation seems more popular.
• It has been debated whether the year 2020 was the tenth and last year in a decade or the first year in a new decade.
