we felt that services like the one we propose works nicer than asking users to change their daily routine, added benefit is that this would proliferate down the entire google reader stack. eg: value if you just use google reader on iphone.
Yeah, no doubt it's a lot easier to stay on the Google Reader stack. With NewsBlur, it's completely separate from Google Reader (other than an initial Google Reader OAuth import of your feeds). Which means I have to write my own iPhone app to communicate with NewsBlur, but that's part of the fun.
It's not a business, just a side project where I learn as much as I can about a huge variety of topics from server maintenance, to pattern recognition, to distributed systems (feed fetching).
