In short, Twitter is a critical success but in a corporate quandary. One could argue that the problem is not, in fact, with the company, but with Wall Street. A sugar rush as Twitter prepared to float drove it to up its IPO price by 30pc, and the ensuing fear of missing out (or “FOMO”) among investors drove it to an eye-watering $45bn market cap in early 2014. This for a company that had just made an annual loss of $645m.
