After the Google Reader demise announcement came out, I switched to NewsBlur, and I am glad I did for two reasons.
First, it gives me greater insight into how each feed is working. I see which ones are dead every time I open the page, which lets me find where they went or remove them. In Google Reader, I had no idea so many feeds had moved. I assumed the authors just moved on.
Second, and more importantly, the "People Have Spoken" feed is great. It pulls great stuff from blogs I would otherwise not read. I am always excited when something new shows up there.
