When you enter a topic or company or search items in the add-a-feed field in Feedly you get a list of suggestions. At the bottom you also get Tracking Tools, either google news or youtube. This works in desktop and ipad app.
I would like this feature in Newsblur. Then you could add a specific search term as a google news feed. I know this can be done if Feedly is doing it. I am liking Newsblur except for this one missing feature
