I'm sure I'm the last person to know about this, but just in case I'm not...this one's for you!
I just discovered Google Reader. It's a free service that will track all of your blogs and favorite news sources. You simply log into your google account, enter the URL's of the blogs you want it to track, and voila! There are all of your blogs! So you don't have to go to each individual blog to check and see if they have updated.
The one draw back is it can't track blogs that are set to private. But since I only have a handful of private blogs that I check, I can live with it. And you can't leave comments from it, and since we all know what a loud mouth I am, that's going to be a bit tricky. But you can click right on the update and it will take you to the blog to leave a comment. Whew!
