I was going to say Google Reader too but have just reconsidered. I do miss it, and the idea that this was a popular way to consume news / content etc. However I can still use RSS on feedly, inoreader and a bunch of self-hosted alternatives. By moving away from Google I am also escaping their all-seeing eye, albeit to some minor extent. In the time since Google retired Reader I have begun to see them as a negative presence in the world. I have moved from Gmail and Google Calendar to Fastmail, self-host my contacts and will move on from Android as soon as Ubuntu Touch or another alternative become fully featured enough.
