It is a good initiative @OP to invite us to join a discord channel in order to discuss Bitcoin and enhance our knowledge about it. But I believe this forum is enough since the forum is already rich with information both facts and fiction, myth and truth about Bitcoin. Besides, we are already here discussing current events of Bitcoin's technology, economy, and politics.
Most of yh active forum users (barring the spammers and bounty hunters), would have a decent understanding of Bitcoin and how it works to not need a regular off forum meeting to improve on their knowledge. And the few who do are welcome to interact here and learn more from the more experienced users; the entire purpose of the forum.
I agree, most forum members here are somehow knowledgeable about Bitcoin so having an extra platform to discuss the same ideas and topics is just a waste of time, IMO, unless we have Bitcoin icons on that Discord Channel that will conduct regular updates, insights and development of Bitcoin.
Your idea is surely a good one and would be greatly helpful to your friends who need Al the expert guidance they can get as they get their feet wet in Bitcoin, but you might not get a substantial amount of users here willing to join in.
True, I admit I am one of those who is content to discuss bitcoin and cryptocurrency in this forum because I am too lazy to jump from one platform to the other. Even my social media accounts has been idling for years now.
