It's a good thing I found this short video today. My aggregator has completely blown up (I mistakenly decided to upgrade to the first new version in over a year).
I've taken the opportunity to switch to RSS Bandit, which has a much-desired feature in giving me threading of articles that I am reading. I just need to get used to a (slightly) new interface. I like the idea of the web-based tools, like Rojo and Bloglines, but I also want to be able to read my news when I am not connected.
