Adding labels to my blogger posts?

(tags blog, tagging)

I dragged kicking and screaming from the old Blogger to the new "Google Account" Blogger, but as you can see from the previous posts, I'm trying out the "Labels for this post", but I suppose I still have to work out the difference between tags and labels.

I have about 350+ posts on this blog so I suppose am very satisfied with Blogger. I do have the wierd "(tags xyz, abc, 123)" structure at the top which I thought I would use later. Anyways, it's now good blog sense to catagorize your blog posts by labels or tags, not by time archive, according to this blog.
