You have a point in that it is somewhat tech-specific. If, e.g., you are in an open source project with 100 people and 20 are on Twitter, 18 of the 20 are raging, manipulative, self-promoting politicians, all with the correct "Twitter Bio" and the correct set of flags.
They use Twitter to intimidate others and promote their clique.
I find that the only people worth reading are the independently minded ones who don't care what others think. In the current climate, they are either journalists or independently wealthy.
