I really like the Feedly iOS interface for reading, but the app needs some work before it's any good as a primary feed aggregator. The main issue is that it forgets the Google authentication after a few days, even after an update which claimed to fix that issue. That doesn't fill me with confidence that the transition to their backend will be as smooth as they claimed.
Agreed, the extension was very invasive and broke Chrome in many frustrating ways. Memory usage was also off the charts, and that's not something I usually pay much attention to in a browser. I'll try Yoleo, I had not heard of that.
