there are many sites out there that do free river of news for free, refreshing the page every few articles is really annoying, and further, it causes problems with the newsblur mobile app with giving the same article multiple times. While I think a premium service is a great idea, especially for those who are heavy users (people who want to read through 60+ feeds every day), not having river of news on the free version is something of a deal breaker for me and many of my associates who would otherwise most likely use newsblur as their primary readers if it weren’t for this bug. newsblur is a phenominal app, I think that this would attract many more users who otherwise think that it’s broken.
also iirc, the ipad has river of news functionality that works really well (even on non premium accounts), but for whatever reason it breaks on android and the web.
