I've always felt that the real good people don't have time for these secretive communities, they'd rather be doing shit so you'll always have the middle ground between mediocre and amazing. I'm sure the "best" (with regards to what they do) hackernews members rarely (if ever) comment because they're too busy being the best, you don't get to the top by talking about it.
This is sometimes true, sometimes not. I know a few amazing designers that are on Dribble all the time, because it's an outlet for fun things they're making that have nothing to do with client work.
By the same token, if you check out /leaders, lots of people at the top _are_ killing it. There are obviously tons of successful people that aren't on HN, but "commenting on HN means you're unsuccessful," is trivially disproven.

but I didn't even say that, you just pulled that quote out of thin air. Of course posting here doesn't make you unsuccessful, but if you are successful you're less likely to be posting here. I at no point claimed the former...

This is also true of GitHub. But both GitHub and Dribbble are places where you show off evidence of your work. HN is more a talking shop.
