Twitter has failed with harassment, abuse, and has been overran with bots. With Civic you can have verified user accounts (no spam/bots) as well as group voting on users abusing the TOS. Twitter is still amazing with sharing information, interaction, and discovery but allowing verified real users would make the experience 1000x better.
The second evolution of this app could be channels for companies, brands, anything non human that people can follow and post to. Think Telegram Civic channel but in a twitter feed such as below. You can follow your channels of interest and chat with interested people.
