Vue’s Discord is working great as I could search for everything since the first post that what created at 06/17/2017. Accessorily there are 62K people who created 776 187 posts archived total, I can query on all of them to find answers to discussed problems.
On Elm’s Slack #beginner channel I cannot go back before the 15th of May 2019. Such a massive amount of knowledge wasted, or at least, hidden.
I’m for asynchronous discussions so I prefer forums over live chats, but if there has to be a live chat system, why Slack over Discord?
