I've been using Google Reader for quite some time now - really like it. I used to use a desktop aggregator because it was a lot more flexible and customizable, but being tied to a single machine eventually did that one it for me. I've found Google Reader to be very reliable, and it gets nice new features from time to time. A couple of weeks ago they added a nifty way to view their keyboard shortcuts, something I haven't been taking advantage of. While using Google Reader, simply hit the "?" key, and you'll get a nice overlay showing all the keyboard shortcuts (perhaps ironically, users of aggregators may have to click through to see the following brief screencast): (oh, you may want to bump down your volume a bit before hitting play, I seem to have inadvertently pumped up the volume)
