I think another boat to consider are those who consume more than they produce. 'Doing' and 'discussing' are both 'producing' activities but much more demanding than absorbing content.
I almost accidentally described woodworking as a hobby of mine recently; I realised just in time that I basically only (so far?) watch other people do it on Youtube. (Not counting fixing/altering things slightly in a more DIY/carpentry-at-a-push sense than woodworking/joinery.)
