I'd be pretty disappointed if CL were gone. I'd be active in Discord, and try to fill the void by searching for other half-decent geeky hobby sites with chat and forum systems, but I doubt the community would provide the same fulfillment that I pull from CL's, since most of them are either considerably less active than CL's, or considerably more active than CL's, which in my eyes would be quite a bit less appealing.
If that does ultimately happen, though, I'd definitely like to put some more time into the discord server. Learn about and implement bots, change the channels around a bit to make it more notable and all that. And cross my fingers we wouldn't lose much of our community in the transition. xP
