Another NewsBlur user here, ever since Google killed off Google Reader. All of my news and regular content consumption, including HN, is via RSS. If a site doesn’t have a well behaved RSS feed then I won’t be able to follow it.
I’ve used a number of blog engines over the years and don’t recall ever having a problem with RSS. It seems like a solved problem on the publishing side.
I do find it annoying when the RSS feed publishes only partial content without making it clear that it’s doing so.
