feedspot doesn't seem to support tags. Is there a comparison chart showing how these services relate to greader features to help people decide where to migrate based on their needs?

No folders or tags? How do you separate or prioritize? I may have five hundred plus feeds and I may not be watching all of them all the time.

I've imported content from google reader, and there's folders, but manually i can not add any.

I like what I see there, thanks.
