Labels

I just realized that I use labels for these blog posts like keywords. That might not be what's intended, but it's damn handy.
It dawned on me when I looked at my label list, and it was huge and there weren't more than maybe 5-10 labels that were connected to more than one post. It's not like I categorize my posts anyway, so we'll see where it leads. Who knows, maybe when I have 10k posts, then the list will look a lot different. How do you use your labels?
