I use blogines.com to read rss feeds. I periodically look around to see if there is something better, but I have yet to find one. That doesn't mean that there aren't some things I would like to see in a reader. Just recently, I was wishing there were keyboard shortcuts to navigate my many folders of feeds. And, alas, this morning I noticed this at the bottom of the list of articles:

Hotkeys: j - next article k - previous article s - next sub f - next folder A - read all r - refresh left pane

It's not huge news, but It makes my life a touch easier, and will help the batteries in my cordless optical mouse last longer :)
