Somewhere along the line, the whole system started to go haywire. Twitter began to feel frenetic, unhinged, and—all too often—angry. Some people quit. Others, like Schulz, cut way back. I felt the same urge, but I wanted to do something less extreme, something that would allow me to keep the baby, even as I drained the bathwater. So I began to take note each time I experienced a little hit of outrage or condescension or envy during a Twitter session. What I found was that nearly every time I felt one of these negative emotions, it was triggered by a retweet.
