Ok on both...
Oh, I forgot to mention, I’m assuming you meant to say; ‘what we want to avoid’.
Me I certainly get all of it, since my background is computer tech.
There’s Pro & Cons on both sides, but given Discord is free, if you have the man power, there will certainly be a lot of people that will enjoy it.
I just look at it like this, having/offering different choices can be a good thing, because everyone doesn’t like the same things.
Many people will prefer Discord too over a Forum.
I’m not sure what your background is with computers, but the Social Pecking Order started like this;
Newsgroups
IRC
Forums
Social Media platforms - Including Discord.
Discord came out in 2015, in the world of Tech it’s a newer platform over Forums, so it has a lot of traction/popularity.
I like Forums, IRC, and Discord, all three have good points.
I would never ditch the forum, it is good, I’m just saying, a lot of people will enjoy Discord too, and it can make an extreme positive impact.
Give people choices, and let them pick what they like.
