Do They Offer Blogging 101?

I'm updating my blog with labels, which means that the posts will now be categorized. This will make it nice if you're trying to look back to a specific post on a specific topic. It will also help newcomers to the blog find something specific that they might be searching for. However, being the self-taught blogger that I am (read: blog illiterate), I am doing this by going into each post and republishing them with the new labels. I hope this is not really annoying if you read the blog through bloglines. If "new" posts keep popping up in your bloglines, and they are really old ones, my new little labeling project is probably the reason. So sorry in advance!
