I know people will hate this idea, but I would like to see what it would look like if they limited the amount of tweets a free account was allowed to send and even deprioritize those tweets to only show up on to their followers. Seems like it could curtail a lot of the toxicity. Obviously the other side of that coin is that it could limit discussions and interactions, but maybe it would show how useless a lot of the interactions are on the site.

Of course, I say this as someone who never tweets. I only use Twitter to aggregate news/interesting people. A bigger question is how can they make a user like me pay.
