This chart shows very clearly why investors have lost faith in Twitter (TWTR)

Twitter reported earnings on Wednesday, and the stock is off about 4% Thursday on news of stalled user growth.

On its earnings call, Twitter cherry-picked some metrics suggesting that user engagement was growing — that is, the people who use the service are doing more with it — but this chart from Statista shows very clearly why investors are losing faith: User growth on the service has been steadily slowing for more than four years, and it has finally ground to a halt.

Maybe Twitter can become a viable business with 300 million or so users, but it won't become the next Facebook, where user growth just keeps going. That's why Twitter is now worth $10 billion, down about 80% from its peak in late 2013.
