Q. I've used Google Reader for a long time with no trouble, but for some reason I cannot figure out how to add the Airfarewatchdog blog. Can you please give me a direct RSS address I can enter into my reader? Thanks.

A. Sure thing, here you go:

feed://www.airfarewatchdog.com/rss/blog/

And don't forget, you can also add specific cities to your feeds as well, and receive fare updates via your RSS reader. Just click here for a list of city feeds.

Have no idea what any of this means? Uh-oh. Better read our guide to RSS feeds.
