I would absolutely have paid for this with my last startup, especially if I could specify which blogs/reddits etc to pull content from. I had a manual process that involved checking 5 blogs and 2 subreddits every day to pick out the top 3-4 interesting posts to link to.
Lot of people in the industry (I'm one of them ;) ) use RSS aggregators like Feedly to do this these days. Feedly even has a buffer integration...bonus points.
