The core posters aren't going anywhere, but they are starting to die off quite literally. There is no fresh blood coming and it's been a problem for a while. Twitter absolutely sucks, but the media is posted there. I have a plan to change that soon, but we really need people using surly first and Twitter second or never instead of using Twitter and then posting stuff here from there.
I think a clip generator tool where people can do analysis of the games/plays or just clip certain segments and post their thoughts would go a super long way.
I also think a season replay/media repository will help keep people here on the site.
I'm also trying to build out a gif repo going so we host the gifs everyone uses instead of having to go to yarn or giphy or whatever.
There's a lot to do to really modernize this place and make it a place that everyone who is a fan should come beyond just a discussion/message board. People just aren't that into that form anymore.
