Thing 9

I should've added feeds this way instead of adding bundles.

Using Google Search was the easiest and most user friendly. It also made it easy to add the feed to my reader. Edublog was not helpful to me. Tlopix.net didn't work because too many of its features were blocked on my work computer, so that was the most confusing.

I found NCTM feed which is useful for me, a math teacher.

I think word of mouth will be a useful tool to finding feeds.
