Feedly is fully integrated with Google Reader. Just install the Feedly add-on in Firefox 3. It will create 4 tags in Google Reader to organize everything. Automatically, all your Google Reader feeds are viewable in Feedly. Feedly will also automatically use your Google Reader tags. When you read an item in Feedly, it is marked as read in Google Reader. Recommending in Feedly will also share in Google Reader. If you annotate a post in Feedly, it will add a note in Google Reader. All of these actions occur simultaneously in both, so have fun, but use caution.
