To me, a forum is about topics and people can discuss them at their own leisure, bumping them in the process. In contrast slashdot, reddit, HN are more like "what topics are currently on", and if only few people are interested in a topic and visit the site apart from each other, no story they are interested in will make it to the front page, and they can't even discuss it "slowly, sometimes", like they could on a forum with a search function.

On reddit you at least get informed of replies to your comments, but discussions older than X are automatically closed, so that's not enough use to shift the balance for me.. I remember when a topic being locked felt like something rather grave, where either mods or users fucked up - now it's built-in. And sometimes discussion even gets substituted with clicking buttons.. which is also not about the topics, but another form of using outside force (something other than words) on words.

I don't think you are entirely wrong, but IME bumping an old forum thread will, more often than not, result in other members getting annoyed at necroing a thread. And while discussion does somewhat get replaced with like buttons, I have seen entirely too many "+1" posts on forums; people want to do something to show they like/agree with a poster even when they have nothing constructive to add.

Although on this site, I don't think I'm alone in only downvoting posts that are flamebait or factually incorrect, rather than opinions I disagree with. There is a bit of an echo chamber effect here, but it is nowhere near as bad as Slashdot or most forums get.

Well, not in mine, in serious forums. Sure, gamer forums, and what have you.

They don't actually take away though, not like people downvoting, because they can't show something being incorrect, does, which I see happen all the time.
