Matt Lewis liked Twitter when it started.
Not so much now.
Once everyone was on Twitter, everyone's problems were on Twitter. The early adopters might have been tech-utopians, but the succeeding waves were angry cynics and partisan cranks who used the technology to make the world even louder and worse than it was before Twitter.
Compounding the problem is that — unlike everyone else — if you work in journalism, you can check out anytime you like, but you can never leave. Being on Twitter is now part of the job, meaning that you can't not be on Twitter. What was once an inspiring place that gave you a competitive advantage became a prison.
