"Twitterized" - means you can no longer absorb anything but simple concepts that can be delivered in a few lines, due to too much time spent on Twitter. To quote some early 20th century propaganda monkey, "The essence of propaganda is to take a complex subject, reduce it to a simple concept that a small child can understand, and then repeat, repeat, repeat."

That's what Twitter is ideal for, and that's what political and media types use it for. Add in siloed echo chambers like Facebook groups and Reddit subreddits... I urge everyone to flush it all down the toilet.
