I've been a Google Reader user since the beginning, and have had an uneasy sense that this was coming for a while. I started building a replacement for it that fits my needs a couple months ago.
It's not ready yet, but I thought I might as well toss up a launchrock page and collect email addresses from other folks who might be interested: http://signup.viafeeds.com
Here are my guiding principles:
1. It's going to cost money. I refuse to 'lose money on each customer, but make it up on volume.' I imagine that for more casual users, this'll be a nominal amount. I won't compromise on this because....
2. I want to build something sustainable, and have it be enough of a profit center for me that I'm willing to focus on it and continually improve it for years to come.
3. I want to build something that I'll love more than Google Reader. I spend at least an hour a day in Google Reader, and want to make sure that whatever I build has the simplicity of Reader.
I have a lot of interesting ideas I want to try out around inclusion of contextual information and the ability to easily save or share articles or clips of articles in multiple ways. From conversations I've had with friends in the journalism world, there's a real need for a product like this, especially one with a legitimate business model.
Regarding where this fits in relative to NewsBlur: I think NewsBlur is doing a lot of interesting stuff, but it feels heavyweight to me, compared to Google Reader. I want a very minimalistic, "just the facts, ma'am" experience.
What do you want to see in a news feed product? Where do you think Google Reader could've or should've been in 2013 if Google had properly maintained it?
