Hm, yes. I think that's actually a function of the posters' ability to do so; and to some degree is a function of the size of the posting audience (i.e., slashdot and Usenet were both better when they were small). Mercifully, this is a pretty niche topic, so I don't see that changing much in the near future. One reason I like slashcode is the ability to thread discussions as I see fit, with moderation to keep dumb/offtopic comments invisible.
I'm not interested in sifting through the "me too" posts, the "please review my site" posts, the "google didn't crawl me¦google gave me PR0, boo hoo" posts, etc. Even if I have the ability to bookmark the individual posts, I don't want to have to sort through tons of these kinds of things. This to me shows up the limitations of the search engine as a presentation tool: while it can give you a gazillion results, relevance is still a substantial issue. This is why books have editors, and why I think there's a strong need for a FAQ here -- or a book.
