It would be better were that true. But sadly, there's are hair-think veins of incredibly useful discussion happening there as well. I have tried in the past to construct in Twitter a timeline that showed me just the very informative or thoughtful comments but it always ends the same way - my worst interests gratified, my better ones unsated.
i think you're just describing addiction. there's always some elusive "value" that you're chasing.
i don't know about twitter, i've never used it, but i find it hard to believe there's anything "incredibly useful" on there. interesting, i could see, but useful?
I've had pretty good success with Twitter. I am careful to limit my followers to avoid cluttering up my feed with stuff I don't want to see.
I mostly follow the math teacher/early education crowd and regularly get inspired with fun math games and other activities to do with my kids. Plus I've gotten a lot of neat books from the library after seeing someone mention them on Twitter.
So for me it's been a good signal-to-noise ratio, unlike e.g. Reddit where I can definitely relate to that elusive value-chasing you describe. Even on HN, the amount of relevant stuff I learn is low compared to the sheer amount of time I've spent here over the years.
