Blog Directories - Should you use them? What are they?

I was on Twitter last night, just cleaning up some people who may never follow me and following lists of people who do follow me...that is another post altogether...and I found Thomas Shea or Tommy's Lists blog. I had just talked about blog directories with Pragmatic Mom and I had not yet gotten around to adding my blog to the any. This post gave me a good list of the directories (which are free - unless you upgrade) and that increase your backlinks and increase your traffic.
