Recently I see a lot of people using Discord to be in touch with each other. Private messages, Servers etc makes the place fun and interesting. I think people love using Discord much more than Facebook or Twitter.
When you find people on a platform, there is a good chance that you can monetise it too. Can Discord act as a home for groups beating its rivals ?
Discord is feature rich, useful, easy to use and almost free unlimited when compared to Facebook groups. I agree that readability is somewhat better even though Facebook uses much more professional colour scheme.
I know a few Discord groups which are very successful. They are active and busy, produce a lot of content and assets. Discord is a nice option as long as we know how to use it.
I know a couple of people who are doing this. But I am not so close that they will tell me how exactly it going. But there is potential for sure. if there is community engagement, that is nice. But Discord is primarily a gamer's platform. That could come in the way if you community is not related to gaming.
Give it a try. I have seen people advertise their Discord servers in forum signature on a lot of platforms. If you feel like doing it, there is a good chance there will be some traffic.
