I finally got Chirp working with websockets! Well, it had worked before, but just sent down all the chirps that existed. Now it updates in real-time when someone else chirps. Though, it sends it to everyone, so don't say anything you'd want kept secret!
Eventually, I'd want to send messages only to followers and have them show up in the nav bar as notifications, but this was mostly meant as a proof of concept, anyway. I'd much rather go write a new sql library for lisp, now, that try to finish everything. At some point, paging chirps so you can scroll to fetch more would be good.
This was sort of my minimum product for this project, but I might polish it more as I have time.
