So the problem is Reddit..
So the problem isn't that people hate the community beta. It's that they hate Reddit.
They hate Reddit because unpopular posts disappear; as they should. Reddit self moderates by using a new post section for each SubReddit. If you want to see what's happened recently you can look at that section and upvote or comment on what you think is cool. If lot's of people like the post it moves to the frontpage.
But people hate the concept that popular posts will be the easiest to find. Coincidentally this makes it quicker to read through what's trending in the community and comment on it. It's essentially a hyper bump.
Lastly people find nested replies hard to read. Personally I don't want to read through 100 pages of a forum post. I'd rather look at the rito responses and those of people with interesting input; in the end what's important is the idea and not the journey to the idea.
And so as far as I'm to understand the purpose of this forum model is to remove the clutter and downtime issues. Remove downtime by having a forum system engineered to deal with the traffic the LOL community provides.
