I've hard similar issues with you, and actually think the opposite to be the case. When I was trying to build an audience, I actually found that it was the low effort nonsense that would get the most traction. At a certain point I was attempting to try to get followers by making a lot of those, and then trying to mix some quality posts in, and had some success. But I started asking myself, to what end? What kind of community am I building that's only interested in low quality junk?
And one thing I noticed about Blogging and Twitter is that they're extremely cliquish. From what I've seen, most people would rather interact with popular Bloggers/Twitter users that they hate or say are idiots than they would with users who have a low follow count/seldom read blog. Sure, there are ways you can juice your follower count so that you're large enough that the big guys will think you're worth enough to pay attention to. But again - what's the point? When you see the complete vapidity of many of these supposed thought leaders, is it really worth it? So what, you can get into the daily Twitter slap fights that they seem to love so much?
I mostly wish their were more places were thoughtful people to find and chat with each other, without having to get involved with petty blog/Twitter vanity games.
