I love RSS/ATOM. The only problem i have is with sites, that don't let me see the complete content inside feedly and i have to open the site in an extra new tab.
Would love some suggestions for this. (other feedgraber, self hosted,...)
Feedbro has built-in Readability style engine that can transform partial feeds to full feeds (you have to set it in Properties for each feed): https://nodetics.com/feedbro/
