I diligently tag posts on this blog, not because I actually think anybody clicks in the cloud to find specific types of posts, but because it's interesting to see, over time, what I usually write about.
There's another way of doing this. Wordle.net will allow you to input the feed for a blog, and it will extract the most common words from the last number of posts.
I'm gratified to see that the most common word in this blog is "data," followed by "studies," "participants" and "blog". The high frequency of "blog" and the URL for this site are a byproduct of my ATOM feed, which lists the URL of the blog after every post.
Unfortunately, the restriction of Wordle.net to the most recent posts means that some words are over-weighted. For instance, my recent post about shilling for products mentioned the word "product" enough times to make that word prominent in this word cloud.
