I am in search of interesting content all the time and mainly Reddit and Twitter serve the purpose. However lately i have been experimenting with Refind app and so far happy with the results https://refind.com/anantshri?invite=2dd6356a26 The app asks for your interest areas and gives you 5 articles a day.
Note: I have intentionally picked topics which are lacking in my twitter or Reddit feeds and could be the reason I get more satisfaction and variation.
