Discord has evolved from more or less being a series of chatrooms (like IRC) to having “threads” that work a lot like how a forum would typically be used.
In the repair community, a lot of conversation about component level repair has moved to Discord channels. Sites like badcaps.net or the Rossmann group forums have comparatively low usage. Nested away in Discord, this information doesn’t show up in search engine results and can’t be archived by web crawlers. When a Discord server is deleted or made private, that information is forever lost.
