In what way is "discord" a better solution than a forum?
So in "discord" you can talk to like minded people... you are doing that right here in the forum. Is discord searchable? Will google find discord conversations? Because the forum is, and google can.
The EEVBlog forum is not a gossipy water cooler type forum where what you say is so unimportant in the scheme of things that it doesn't matter if it's visible for an hour let alone a decade, this is a technical forum, people have mostly technical discussions that people in the future may wish to find and refer to.
In short, the EEVBlog is not a chatty place, it's a place for in depth detailed discussion.
If you want a transiently chatty place, fine go make a discord, or an IRC channel, or whatever, but technical discussions do not belong there IMHO and 99% of EEVBlog forum is technical discussion.
