I noticed that, the 2016 election cycle completely has killed Holla Forums's quality shortly after the "alt-right" was created and the "kek" meme really kicked up steam. I think that goons or other outsiders created the kek meme and the other related memes that turned the discussion into shit. Have you noticed that, when enough posters are spamming the board with memes, instead of discussing content, it destroys the board quality and attracts similar posters? Now granted we don't have the same activity of posting right now, but it's still a problem.
Then, we also have the problem that a huge amount of posters here are reddit users. If you actually make a thread (like this one) pointing this out, you will notice that a few of them will out themselves, or say that they found out about this place because of reddit. I think that it's important to notice that the 2016 election and GG were both events that caused a mass migration of redditors into the pool of posters here, as they were both major internet-wide happenings that required the kind of anonymity that imageboards provide for serious discussion. We know that GG and moot's attempt to kill Holla Forums was able to kill the general quality of 4chan because of a combination of reddit immigrants from GG entering the site and older posters leaving the site to post on Holla Forums. I think that the 2016 election is causing a similar migration, but I don't know where people are leaving too. Personally I haven't posted on Holla Forums for a while because of this.
I also want to try and point out another effect of GG- and this was the merging of the Holla Forums and /v/ userbase. If you'll notice that before GG, the /v/ and Holla Forums userbases were a lot more distinct from each other, but after GG I noticed that a lot of the /v/ mentality came into the Holla Forums userbase, and I think that there was a distinct cultural shift in Holla Forums since then. I personally think that the reason that the Holla Forums userbase was so susceptible to memes that detract from the actual discussion and instead are just pointless references or "brand wars" is because /v/ discussion is filled with this kind of thing. Then, you can apply /v/ shitposting to Holla Forums ideas, and you have a userbase that is undermined by this mentality.
I think that the result of all of this is that there is a big change in how Holla Forums works… we have the kind of blind mentality that reddit has that favors in-group thinking and doesn't tolerate disagreements- I think that this is why a lot of users will compromise their values when Trump does something that is arguably bad, and will defend him no matter what, but without making arguments- I think that a lot of these posters are here from reddit, since this kind of blind faith in a set of shared values is something that their website is designed to breed. I'm not talking about people who argue, but the kinds of people who post memes instead of arguing. It's what they do because Holla Forums has no "downvote" button for them to press.
And quite a lot of threads are just spam by now, from either actors from other sites or boards making a concentrated effort, or by misguided people who think that they are making a contribution to the board instead of being a cancerous entity who is helping destroy it. I think that's how a lot of people who have adopted the "reddit mentality" think- they think that they are helping the website, instead of hurting it with their presence.
Now, I don't think that there should be no fun allowed, but I hope that I'm not the only "pre-GG" user who has noticed these changes to the site.
