I haven't used the app or my Sony Reader in months - pRSSReader on my Tilt is just much more convenient - - so I'm not actively fixing or enhancing it. Nontheless it represents a fair amount of development effort so that's why I'm putting it on Codeplex - so others can contribute if they want.
I'll look into the bug report issue; publish/subscribe and bug reporting should still work. If I can move bug reporting over to Codeplex that would be better.
