I also noticed some people either posting very rarely or not at all recently, from the ones that usually had something to say, very well articulated too.
It's unfortunate, maybe the general crypto situation or economic worries have something to do with this. Health issues could happen too, as you also mentioned, but let's hope it's not the case.
The Liotes guys had a mission recently about motivation, which seems appropriate in the context... Maybe they lost motivation, and they need to get it back somehow.
You're right. Motivation could be a thing, but I don't think it could have been motivation since these two guys have constantly posted for over 5 years without much break in between. However, I think I'll be looking at their accounts to see if they're active. Surely the first guy stoped posting because of DVs, but the second one must've been something entirely different.
It feels weird to not have people who knows what they're posting not to be active as before.
