I think going OS is a bold move, and with a bit of luck (and community interest) it should help propel some interesting developments and keep it at the cutting edge in the post-reader landscape... and if that expand all thing annoys me enough, I could just code it up myself.
@mtthwp: No, Feedbin as a service will still require a fee; however, the code itself is now open to anyone. If you really wanted, you could go host it elsewhere yourself (for far more than the monthly fee).
"Free as in beer" and "free as in freedom" confuse me too, because beer sets you free, and freedom has no monetary definition for some people.
In this post-GR era, opening up the code like this really opens up opportunity for serious innovation. As an aggregator/reader developer I look forward to digging in and seeing how you solved some issues.
I switched to Feedly from Feedbin earlier this week and now I feel bad. Will immediately switch back.
