From a Washington Post story by Taylor Lorenz headlined “How Twitter lost its place as the global town square”:

Alex Pearlman, a stand-up comedian in Philadelphia, woke up one morning in June and turned on the local news. A portion of Interstate 95 had collapsed. Pearlman thought it was the type of thing people should know about.

Five years ago, he would have turned to Twitter to spread the news. But on that Sunday morning, he picked up his phone and made a TikTok — which quickly amassed more than 2 million views.
