Someone should make a Twitter-like that verifies posters at various levels based on humanness/geographic locale and other characteristics.

Then posters could limit conversations to those with >90% human score (with score going up when twitter has more certainty that you are a human) located in the US (for US political conversations), etc.

I'd certainly pay a few bucks to be verified and contribute much more often to conversations than I do now, as now it just seems like screaming into the bot void.
