For those of my readers who were using Google Reader, here are my comments
1) backup your data, read this : https://support.google.com/reader/answer/3028851
2) for the web gui, there is a one-click migration to Feedly : http://feedly.com
3) you can import the OPML (Outline Processor Markup Language) file from Google Takeout into Microsoft Outlook (right click on RSS Feeds –> import OPML).
Maybe you want to forget about RSS and switch to Google+ or Twitter or read orafaq or orana or install your own aggregator on your web server (e.g. tiny rss)
I”m going for Digg reader, very similar of what Google Reader was doing as well as the look and feel.
Also one click migration…
It forwarded me to Internet Explorer 8 and older versions are not currently supported
There’s always side effects of any change… 🙂
