To be honest, I might actually read the United forum if something like this were implemented.

It gets really, really old to have 99 posts of "Changes You Will Like" and "$mi$ek" for every useful post with content. The UA forum was always super-busy and hard to keep up with, but now it's gotten to the point where the volume is so high and the signal-to-noise ratio is so low that it's just not worth reading anymore, even occasionally, except for a few specific threads I subscribe to. I get all of my United news from friends who fly United either via conversations with them or their posts on Facebook.
