a.k.a. the 90–9–1 principle. Does the Fediverse follow this rule, or are there more creators here as early adopters? Are you a creator, a participator or a lurker?
I think OP is counting commenting as being a "participator". I pretty much followed the 90-9-1 rule with my 11 year reddit account (90% lurk, 9% comment, 1% post) and likely will do the same here. I was always very diligent up/downvoting things based on value and reporting violations at reddit though, which I think gets calculated into their engagement metrics, unlike at Lemmy if I am not mistaken.
People use reddit (and hopefully Lemmy) and not just a news aggrigator because people value the comments and discourse on content as much or sometimes more than the content itself. (Granted - this may be subject specific)
