For those who haven’t yet done anything about their Google Reader subscriptions, now is your last chance. Head over to Google.com/Reader , got into settings, and hit the export button. This will send you over to Google Takeout and will provide you with a .zip file of your subscriptions.
If you haven’t found a good alternative yet, I would strongly suggest Feedly. Feedly is a multi-platform RSS reader that has a fool-proof import process from Google Reader. Feedly has an iOS and an Android App (both free) as well as a nice Chrome web-app. While not flawless, Feedly is certainly the most well put together Google Reader alternative I have found.
