I run a similar service
https://lettergram.netI like this layout - in terms of it being straight forward and easy to scroll.
I am curious why some of the stories are trending (for instance (5 sources) at the bottom:
> 1,000 wild horses to be rounded up in Northern California (seattlepi.com)
It appears this is just following / aggregating standard news outlets (I'm guessing ~50 or so). Then clustering the stories based on some sort of fuzzy matching.
Pretty cool IMO, but care to elaborate on the machine learning portion?
