It's nice that lots of folks are jumping in to fill the void left by Google Reader, but if there's one thing that the Google fiasco has proven, it's that we need a standardized, open protocol for synced RSS reading, to break vendor lock-in. Maybe something as basic as hosting OPML on WebDAV, with extensions to support read/unread states, sync dates, and other reading-related metadata.
I've switched my calendar and contact list away from Google to my own server running OwnCloud; it'd be nice if I could sync my feeds there as well, with support for a common protocol available in lots of clients.
