* Feedly has a simple interface which is much more like Google Reader. But it depends on a plugin (or an app) rather than being an allwhere accessible website. Their Kindle Fire app seemed to load content extremely slowly, and its interface wasn't a simple list. And it's free, so I can't be a customer and I don't know how they earn money.
* NewsBlur is complicated and unresponsive. There are a lot of inscrutable unlabeled icons, and I don't understand why an arrow follows the mouse. It's a paid service - I can be a customer - but I don't know how sustainable NewsBlur will be with its current issues and with subscription as its only source of funding.
If NewsBlur seems solid by May, I'll gladly pay them. If Feedly seems less like a faceless data-miner by May, I'll use them.
Really? It is a feature for better reading, so you can can easily see which line you are.
I am working on making the UI more user friendly and adding OPML import/export.
It's going to be supported by advertising with a subscription service for premium features and no ads.
Still working on the UI to show the article content and links to attached files.
Overall I found Feedly to be better.
