We out here!
I've been a full-time lurker only at Reddit for over 10 years, never made a single comment there. Never even created an account. I suppose I don't have any interesting reasons other than I never really had a desire to engage in those communities but did like it as a lookup resource. I'm an 'internet old-fart' that has always preferred forums and even ran a few back in the day.
The fediverse is the first 'newer' social system that gives me those old-school forum vibes while at the same time being fresh and more connected. It feels like this is one of those 'shifts' in internet history and is a good time to hop back on the internet social train.
