Excellent idea!
I don’t mind the occasional dup. It helps me not miss the important stuff.
I’m a dedicated FReeper and I spend at least an hour a day scrolling and reading, but I can’t catch everything! lol!
Sometimes I’ll pass by an article. But if I see the same article posted three times by different people, I’ll see if there’s anything there that I was dismissing. Most of the time, if it’s worth a dup, it’s worth reading.
