This is a great point, having experienced just this firsthand just recently. I launched an online boardgame and tried announcing it in a bunch of different places - boardgamegeek, some relevant subreddits, elixirforum. While the other forums got views, the one that actually got some real engagement and comments was the boardgamegeek forum, arguably the "crappy" one of the three. Although it's "crappy" only in the sense that it's pretty no-frills and just feels kind of old-school.
