I won't lie. I mostly don't engage with content I see here. I didn't do that when I was on Reddit either and mostly for the same reason: I don't really have much to say and, even when I do have an opinion, I don't usually want to engage in what's often a protracted debate about something that will probably just end up being frustrating.
That's not to say I haven't had positive experiences on the Fediverse - I've had more here than anywhere else - I'm just not particularly motivated most of the time.
