How is Twitter holding up in 2021? It depends on how you look at it. As a service, it is trying to innovate with new features, but as this piece argues, it is kinda stuck: Twitter Is Stuck With Itself, Too – The New York Times.
As a company, though, it is doing well. For example, it continues to be profitable: Twitter Continues Its Profit Streak, While Still Shedding Users – The New York Times. The shedding users is a concern.
And compared to other services like YouTube, it is doing ok, as this piece shows: YouTube Is Underwhelming – The New York Times. In fact:
Twitter, which is not so hot at money, pulls in roughly double the ad sales on average from each of its users compared with YouTube.
Perhaps it should be acknowledged that the early social media companies like Twitter and YouTube are mature now and their growth and innovation peaks are behind them. Maybe they will continue to be like Facebook: mimicking every new company in the hopes of draining off some of that enthusiasm.
