JON GABRIEL: Twitter Slides Further into Irrelevancy. “Twitter used to be interesting. I signed up a decade ago and quickly became addicted. You could meet smart people with similar interests, funny people with disturbing interests, and get breaking news a day before the cable nets got around to it. A lot has changed in 10 years. Today, Twitter is mostly dumb people yelling at each other and self-appointed hall monitors trying to shut down accounts they don’t follow.”
