Twitter was great and I think anyone who thinks otherwise either curated it to be awful or didn't really use it at all. Your Twitter experience was defined by who you followed. There was sports Twitter, political Twitter, science Twitter, weird Twitter...there were thousands of different spheres to put yourself in.
If you followed political accounts...yeah you set yourself up for a toxic experience. But I followed funny people so my experience was great. A seemingly endless series of one liners, comics, and weird observations.
