Silly Justine lecturing people when most of them, including me, are just here to shitpost. lol
On a more serious note,
Depending on what a person is seeking, it can be a great time or a bad time. For example, if you are looking for large voter support, now might not be a bad time as much of the crowd has left the chain. If it's audience someone is looking for, I don't think the current state of the platform can offer much more than it does.
As for the lack of engagement, sometimes it's hard to have meaningful interactions. Take some of the tutorial videos or stat posts, what am I supposed to say to those? They are useful info I will clip away for sure, but there's not much for me to say besides the "no shit, Sherlock" comment on the numbers. Okay, maybe I will ask questions if certain parts aren't clear. But yes, a lot of stuff are just not interesting at all.
Take some of @berniesanders' posts, for instance, people engaged. I'm sure many were just there for the votes, but the point stands. Many "content creators" don't create anything for people to interact with.
Attention span has already been mentioned here, so I won't say anymore.
