Google Reader is officially gone, but you still have until July 15 to export your data via Google Takeout. Once you've exported your data, you can begin importing it into alternative readers, like Digg Reader. Here's how to import your Google Reader feeds, including starred items, into Digg Reader:
Step 1: Go to https://digg.com/settings, then under the Digg Reader section, click "Upload."
Step 2: Click on "Upload your data," then select your Google Reader Takeout archive -- the entire ZIP file -- for upload to Digg Reader.
Once the import completes, you should see all your old Google Reader subscriptions, as well as your starred items under the Saved section.
