Anyways, I’m not saying your request is unreasonable. Just offering a counter perspective.
Case in point: the other day there was a posting about scanning old scrolls for text, and I found the topic dull. Reading the commentary I learn about the Ea-Nasir tabled[1] and found it both amusing and interesting. I also learned there's a whole subreddit dedicated to this topic, and reading through some of the funnies I decided to go back and read the actual article about scanning the scrolls. I then learned much more than I thought I wanted to learn about true intricate process and labor involved in doing this work, and found it quite interesting indeed.
So yeah, I'd much rather a high percentage of posts on this site continue to be about topics I have no immediate interest in, because you never know...

I find general News sites unreadable. Just trash, shitloads of advertisements, they try to blur the line between news and advertisement. You can't even navigate this stuff without an adblocker.
Using an RSS reader with selected feeds, helps a lot. Especially since you will have many blogs that rarely post something and without an RSSReader you would not be able to follow them.
