I like the chaos of chronological posts, much like tumblr, but yes I agree there's a lot of duplicate content and I wish there were a feature to assist either better discoverability of pre-existing articles while still allowing for frequent opinion ones ("How I got into tech"/"My fave extensions") to be given space.
I would like to point out this community is much more friendly than stack overflow and I'd rather it remain so. I'm into the related-content idea, or even curated lists like on twitter.
