The spirit of the discord is different from a reddit like forum space, due to the nature of how posts are presented. I prefer the reddit/lemmy format, but of those who migrated from the sub to the discord, im sure some prefer discord, including the abikity for voice discussion and to have large community discussions.

Additionally there are many groups on the discord that are not yet on here, such as the internationale groups, the struggle sessions groups, the ideology groups, and the same atomization of hobby groups. If any of those are your main area of interest, you are better served on the discord while the chat is still slowly ramping up (as they should to prevent raids)

Tl;Dr the chat isn't "done, done" yet, and people prefer the format of the discord to the current chat. A slow trickle for now is fine
