Facebook has about 2.5Billion monthly active users.
Instagram has about 1.1-1.2Bn monthly active users.
Twitter has only about 300Mn odd monthly active users.
This is expected to grow at least 2-3 fold in the next decade. Might definitely happen sooner too.

Rithesh Agarwal follows me (I don't even know why, probably because I was tasked to do the blog for Oyo, but then COVID put the project on hold)
