Hi Sam,
Why not create a little user survey, to get an idea of the community that is growing around Newsblur? It would be good to know a little about your new members (like me) and your diehard “I was using Newsblur before it was cool” types.
It would also be a chance for us to tell you how we use the app and website. For example, I read RSS feeds mainly on my iOS devices on my commute, where there is no consistent Internet access, so offline features would really help me… But am I a typical or atypical user or not? I just don’t know. Do you?! It would be good to read about this kind of information on the NewsBlur blog, assuming it does not giveaway competitive advantage over competitor products.
