We have started to upgrade feedly from the Google Reader backend to a new feedly backend. As part of this upgrade, we will automatically upgrade ALL your feeds, your category/folder structure and up to 250 starred articles.
Based on popular request, we are going to try to migrate the articles you read in the past and assigned tags to. This way all the gems you have collected in the past will continue to be accessible when Google Reader goes offline in July.
But we need your help regarding upgrading your tagged articles.
