Growth has been consistent for years, if you squint to smooth out big swings. It's linear, which is about how we like it.

Uniques are up to 4.5M or so per month, depending on how you count.

There's one intriguing exception to the linear growth: the number of submissions has been roughly flat since 2012. Comments, votes, accounts, page views, basically everything have all grown at about the same rate, but not submissions. I'm grateful for that, because we don't have any moderation capacity to spare. But it's interesting to speculate about why.
