I mostly consume my RSS feeds on the London Underground, where 70% of the time you don't have cellphone or WiFi signal.

While my preferred RSS reader NewsBlur can download everything up front, for offline use, I tend to find a lot of sites truncate their articles (with a 'Click here to continue reading!") or just post a headline and a one sentence summary.

This makes me dislike using RSS, not because of the technology, just the way it's delivered these days. It's fine (if a little irritating) if you are online all the time, but offline it's practically unusable bar the few sites that offer full length articles
