As a long time Google Reader user, I’ve been looking at alternatives for use on the desktop, laptop and mobile devices.
I’ve had a go with tt-rss which running as a web application on one of my colo servers is perfect for desktop use as I see the same feed (with read/unread and starred) wherever I login to it from, but does require an active internet connection which is not possible on disconnected laptops, granted Google reader has the same issue. For my iPhone, I installed the tt-rss Fever API plugin and installed Reeder on the iPhone to give my offline reading.
I’ll see how it goes…
