I too suffer the fate of over-documenting.
What I have noticed over the years on some people's projects, is that unless people are struggling, usually there's just not much to say about it. Especially after the first 10 or 15 posts, it's more "check up what they've gotten done", the general excitement and encouragement gets repetitive. It just adds to the noise.
Also, Cunningham's Law: "The best way to get the answer on the internet is not to ask the question, but to pose the wrong answer." People do love to correct wrong things, not just to be negative, but, to be able to contribute.
Often when people do things well, you just nod and move on. There's a guy on the DIY EC forums that's re-creating an entire Porsche from scratch. Like, tube frame, all the panelling, all of it. Who among us can even approach that? It's amazing. And yet, there's often very little commentary. ... what can I contribute to that discussion? Dude is creating his own panels, from scratch.
These communities are also fairly small, so there's not a lot of participants. Even then, I check in every day, and I only read maybe 10% of what gets posted. I reply less than once a day.
Sometimes I think "No one's watching this" and then look at the numbers. Likewise for Youtube, I've got several videos with over 100k views. That's a football stadium, watching a video on rewiring transformers or wearing mismatched clothing after an apocalypse to fit in, not exactly mainstream stuff.
