I did and it's quite good, the problem for me is that I don't always read my feeds on the same device, so having a cloud service I can access from all my devices is very important to me. So if I read something on the PC it doesn't show anymore as unread on the tablet and the phone, etc.

I could export my feed list in OPML format from feedly and then import it in Tidings, but then the two would not talk to each other (unless things changed since the last time I tried Tidings).
