Feedly syncs directly to Google Reader for now, and will migrate your feeds off google reader when the time comes.
They have a post simplifying the transition from Google Reader to feedly.
Feedly runs in the browser and on various mobile devices.
It supports categories for feeds like Google Reader. It supports
k keyboard shortcuts for navigating between posts. A “tiled” view can be readily configured.
Both Lifehacker and CNET have been quick to dump out some options for alternatives. I think in terms of reading on the web and on mobiles (all the below have Android and iOS apps) the best options are:
- Feedly – Probably the most popular alternative, syncs directly to Google Reader for now. Main downside is that using it on the web requires installing a browser plugin.
- Netvibes – An RSS reader that also acts as a dashboard app (like iGoogle). Looks like an emphasis on social analytics for paid tiers, but the free level is fine for RSS reading (import Google Reader data instructions).
- NewsBlur – A nice simple option. Free for up to
64 feeds12 feeds [homepage copy is out of date, sign up and it only lets you turn on 12 feeds], the paid option is only $1 a month for unlimited. (import from Google Reader using this link)
Some generic instructions for exporting your feeds are available from the Data Liberation Front.
If you don’t mind self-hosting it, or finding someone who will, Tiny Tiny RSS is a Free Software web application with a similar look and feel of GReader. It comes with a mobile web UI and there are 3rd party native apps that interface with it.
