Judging by your responses (all be them few) to my poll about how many blogs you subscribe to...I think an informative post is in order.
I think the easiest teaching tool I can provide is a link to this post.
If you only read one blog, Mom and Dad, this might not apply to you. But, if you read more than that, subscribing to blog feeds in a reader will definitely save you time AND keep you from forgetting about some of your favorites!
