Idk maybe I'm still sour after they killed "We are hunted" 10y ago, but I feel Twitter acquired a number of companies and yet remained virtually unchanged for years.

They acquired WAH to merge it into Twitter Music that they later killed. They bought Vine and wasted its potential, idk if Periscope is still alive or not (also acquired).

Maybe this time it'll be different - their recent acquisitions of Revue and Chroma Labs (which I guess became Twitter Spaces) seems to be kind of working so far
