I saw a very interesting blog at 37 Signals on this quote
“The things you do more often are the things you’re going to get good at. …”
It’s by Jason Fried from an interview on the new workplace for the new normal.
One of the reasons that I highly recommend tag clouds for your blog, is that tag clouds let you see what you are really writing about. The stuff you write about often is likely the stuff that interests you. Whether that’s a part of your job or not, your passion will often shine through over time with a set of topics that you often write about.
What does that mean? It means that maybe you want to refocus your career, or training, in the areas that drive you. The largest items in your tag cloud.
