What is the difference between personal and private feeds? Can I add items to personal feeds from Feeds Reader?
The main difference between personal and custom feeds is that personal feeds work in Feeds Box and custom feeds work in Feeds Reader.
On further steps of the personal feeds development process, we plan an option which will allow you to add items from Feeds Reader to your personal feeds. And with time, personal feeds will replace custom feeds completely.
You can now freely use both personal feeds and custom feeds. Upcoming changes won't interrupt or disserve your content sharing process.
