Not only does it take a long time to receive a comment, but there aren't as many posts either. I am outraged at this fact, as it was interesting to see a variety of people online at one time, and be provided a variety of players to communicate with.
I am not sure how this can be fixed, but I'd prefer if Riot could make boards more active, or revert back to forums for the activity to come back.
Daen5 votesRight so, here is the most basic communication concept on anything curated by Riot:
#Community Activity is Dictated by Riot Activity
Want to know how to fix it? It's not up to the community, it's up to Riot. The more Riot communicates meaningfully, the more community presence there will be on this platform.
There's your answer. :P
Zielmann2 votesI agree with everything here. I wish it weren't the case, but that doesn't really matter. Hopefully in the next couple months, they'll pick back up in activity again. I know that lately they've been pretty busy with Worlds and preparing for The Harrowing and Season 5 changes.
DRAGON BALL YIII5 votesThe entire format of this garbage feels terrible. Very reddit-like. Horrible color scheme and interface. There's nothing to do but go back to a traditional forum format. Other than that, nothing will help revive this graveyard.
Kat Head4 votesBecause they are reddit and the color scheme is awful.
Falconone3 votesI mus say i wish me the old forum back. Dont like the reddit style and well Riot is not that active since a year on the forum and this board... Iam from the EUW and must say in Season 1 and 2 there were more rioter online, now they are almost gone... ZenonTheStonic is in the creative team and left the community managment. no one followed into his steps.... I think something went wrong. Where are the Community Managers and the other rioters which we saw long time ago here? Also i think this board style makes it harder to find the right stuff. Dont know.... I want the old forum back.
Maximum Can1 votesyou see this sort of thing all the time. site owner drastically changes the layout without consulting anyone and then gets offended when people ask them to change it back because they worked soooo hard on it 
don't expect it to be reverted ever. get used to it or leave is riot's new modus operandi.
Zielmann2 votesOne of the biggest things that can help would be for more people to actually change the sort every now and again. I fear too many people leave it on Best or Hot, and it basically just perpetuates the topics that already have a lot of attention. If more people would switch to New or Recent more often, then some new threads might have a chance at surviving a bit better.
Roll in Grass1 votesI always keep mine on new. Best and Hot are interesting sometimes, but I want to see what the entire community has to say rather than the 1%.
Zielmann2 votesSame here. Best especially is just where all the circlejerk threads fall. It's practically a useless category, in my opinion. Hot at least shows popular threads that currently see activity. So I keep it on New most of the time. And almost more than the community doing it this way, I almost hope some active Rioters will go to New or Recent to check what's fresh and leave some feedback there. I worry they're only going to look at the threads that are already popular.
Frrz2 votesI just want GD back. I miss my daily dose of general League QQ. Gee Dee is full of unrelated crap about computers, cafes, and non-league things. WHERE IS THE SECTION DEDICATED TO LEAGUE QQ?
Raptamei2 votesThis board is boring.
Dota 2 doesn't have a real forum either, so I guess Riot wanted to copy them? Idk.
Wasted Smurf2 votesThis is a very real problem that needs to be addressed. Unfortunately there aren't enough board members to bump this thread into heaven fast enough. Reds where are you!!! There should be an ask for Red button.
PapaSmurfsShaft1 votesRiot put all the junk threads no1 cares about like "look for x team" so 90% of the threads on the front page arn't troll or rage threads like old gd.
I miss gd :(
Zielmann2 votesThey really need to make the Team Recruitment threads not show up on the main Boards summary page. It does make it harder to find interesting discussion topics because they get flooded out. I was hoping the recruitment section activity would die down quickly, but it doesn't look like that's the case.
Wasted Smurf1 votesBump. Make a change Rito.
