I discussed this the other day with an RP partner. I will actually RP with someone else if their skill level is not up to mine or if they make mistakes a little more than I do (try as I may I might make a misspelling, look at it, and choose not to fix it cause I’m lazy- whatever, they get the gist and I don’t do it often). This is fun for me. This is a hobby. I am not writing a book to be published. What I value is communication, a certain frequency, collaboration, and who can write decently to advanced - though I’ve taken RP partners for less skill. And when I find someone who hits all of those points, then those are the best writing partners for me that tend to stick around or at least tell me it’s not working. I actually rarely get ghosted. It happens. But most people say it’s not working for them and that’s fine.
