I've been trying to use Discord more for a bit and I just don't see how it managed to replace forums. What it got going for itself is that casual conversations are easier and topics may change dynamically (within the channel's scope). But the problem I keep experiencing is that as soon as a topic shifts to something I can't say anything about, all I can do is sitting it out. Forums allow you to engage with any topic at any time, which suits me more.
