I was using Rososo but it's been having troubles for the last month or so. I would love to find something does exactly what it does: let me know when there have been updates to a page since I last viewed it. That's it. It doesn't keep a list of unread posts or or anything. It just presents me with a list of RSS feeds that have changed since I last clicked on their link. That's what I'd love, but I'd settle for something slightly more complicated.
Mostly, I want something that will not expect me to read updates in their own provided viewer but makes it easy for to view the update in its native habitat (actually on the website of origin). I've gotten fed up with waiting for Rososo to get fixed but I don't want to go back to something so complex and distracting as Google Reader.
It looks like Rososo is waking up.
