I'm curious to know what you mean by "impulse" posts.

Posts with very little thought put into them. You log in, you see an opportunity to do something, you respond before it's too late, and hopefully you can do so again before your battle with the orcs gets buried by all the flirts in the bar and whatever the hell everyone else is doing on the pirate ship. You post quickly to do something in the story. There's no time to think. You are encouraged to respond, not do something interesting. You are posting on impulse.

For you, a discord RP sounds great. especially if you don't care about stuff like post length or quality. Myself, I like the writing more than the roleplaying. I like having some time to think about what my characters are going to do, and what sort of drama I can pull everyone into as their GM. I also like that I can balance some of the slower posters and faster posters because in not logging on for one day, they didn't miss out on an important event. Also, I find pure sandbox RPs infuriating and will always insist on working with everyone, co-gm or not, to do special things with the RP.
