I've been blogging on and off for more than four years. When I started, Blogger did not have tags or labels for posts. I really don't know when they enabled that feature but I've finally caught on that they've got it and I'm getting on board.
I know my blog is all over the place subject-wise. I am slowly labeling my posts, but please be patient with me. I have 334 posts and it's slow going for me. The numbers may be changing rapidly as I add labels (because goodness knows I don't post with regularity).
Of course, the worst part of the labeling process is deciding on the labels. Right now, I'm trying to stick with pretty broad categories, so "homeschooling" includes my philosophical thoughts on homeschooling as well as knitty gritty booklists and how we do things around here.
