Overall I basically despise Twitter. But I don't think you have the right concept about what it's for. If you want to read incredibly insightful stuff, look elsewhere, in books.
But if you want to help reassure people of their sanity in cultural fights, Twitter is where a lot of the fighting happens. But even there, take note, the fighting is not to persuade people. That's basically impossible, unless people are really on the fence. It's all about reassurance of sanity among people who are already your allies.
