I tried to follow a number of prominent scientists, people doing programming language research, and various other technical topics to experience what you describe. Almost every single one of the people I followed devolved into commenting on politics and niche social issues more so than the technical topics I followed them for, so I gave up. There were only a handful of exceptions like one person that makes commentary about niche literature I enjoy. The format and culture of Twitter seem to inherently discourage thoughtful discussion and amplify politics, rage, and zingers/gotchas.
