I agree that people have the right to speak their minds, but why cap it at 20 "messages" per day? Is this backed up by any psychological research or did the team set it up arbitrarily?

I'm thinking if I want to really use the app, I'd like to personally control how many messages or views I'm bombarded with. Perhaps I want to hear something every waking hour of the day (so ~18 messages). But maybe some days I would like much less or much more. Why should Vint control my ingestion of messages?
