I am more on discord than the forums, mainly for the versatility.
While it does have some drawbacks like no specific topics and stuff which can be hard for language learners, in more beneficial severs for langauges they often have natives or experts that people can ping for help understanding a grammar point or a document/pin with a bunch of resources to look through. Honestly I just join the country server’s of the language I’m learning… I’ve come to realize that my Spanish isn’t really great and while I’m literate I need more practice but I just explain it’s hard for me and the people in the server are accommodating and correct my dumb grammar mistakes.
It’s kinda similar to the forums in that you can chat with a bunch of different people with a variety. You can servers based in like 20 different countries.
You can have a bunch of channels or threads and there’s a bunch of variety. Often in a good server there’s hundreds of online people so in a moderately popular server you’ll never be bored. I think people like the layout of the servers and how discord itself works. The UI / UX design is just miles ahead in my opinion which has nothing to do with the company hosting on the forums itself it’s just how discourse works. Also there’s a lot of customization, although for a price, but people love nitro and customizing their profile, etc.
The voice chats are also pretty great and people can host classes, lessons, games or just talking. I mean I’ve been on discord since I was in 6th grade which has been a while so I really do like it haha.
I think the forum have some benefits though over discord. You can do lengthier roleplays on here, there’s a larger character account allowing for more detailed posts, interactions and more meaningful length conversations. It’s also more organized in a sense for roleplays and lengthy discourse. You can immediately jump up to the OP post where links, resources and more are.
It’s more moderated and whether that’s a good or bad thing depends on who’s hosting it lol. That’s why you got a specific type of discord, “toxic servers” which is toxic like the name suggests in the sense of low moderation and a lot of out of pocket stuff happening haha. A lot of discord servers aren’t very well moderated unless they’re learning servers or an official company’s server. And also it’s harder and less beneficial to raid the forums than to raid a discord.
