Pro Very good and simple interface
Riot has a very simple interface, adding the ability for more unexperienced PC-Users to use it.
Con Future of Campfire is uncertain
37signals have "changed direction" away from Campfire, focusing on Basecamp. They've ruled out shutting it down, but at this stage it's uncertain whether it'll be spun off as a separate company, sold off, or run in maintenance mode without any new features.
Con No private one-on-one conversation possibility
Con Does not show who's online
Con Still in active yet early development
There is clearly a User Experience issue esp. in web version which the developers are aware of and are working hard to improve. They've got the concept concrete, so UX won't be an issue in no time. Most often used parts are functional, but some are yet not.
The success of riot depends on how fast the development is, or it'll get outdated too quickly as developers of Signal and Telegram have predicted.
