Every interaction you have with a social network nudges you into one mode of interacting or other. The biggest deviation from the norm with Twitter is the ideas of quote-tweeting and subtweeting, making a new post rather than replying to something you disagree with in the comments. The automatic signal boost this achieves incentivizes it strongly, and when the larger account is the quote-tweeting account, they are inclined to hear reply comments almost exclusively from people who support their critique. The structural decision to make this form of interaction easy and productive leads to very Twitter-specific sort of toxic groupthink. "You, a Twitter nobody, just disagreed with someone on their misinterpretation of a well-documented point of history. In response, they made a new post to their 700k followers calling you a chickenshit know-nothing. Your followers heard nothing. 300 of their followers have piled on to elaborate on your faults." This used to be limited to the sort of instant cancellation associated with "Central Park Karen," who IIRC went viral just after boarding a flight and was fired before she landed.
