Topic Clouds Are Popping Up Everywhere...

When a good idea comes along, you can bet that companies like Amazon will recognize it.
Blogsite's Topic Cloud

This week we roll out MyST Topic Cloud for general availability and related to this idea, I happened to notice Amazon is using a similar approach to communicate the contents of books.

While looking at some of the interesting books authored by one of our newest customers (Doris Wild Helmering) a famed guest on national radio shows like Coast to Coast, I noticed the new Amazon Concordance, a topic cloud for each book. Doris will be delighted to know that her new blogsite also has a topic cloud.

And Guy Tavor has created a cool tool - Newwzingo - a tag cloud for Google News. I use it frequently.

Topic clouds are useful because they quickly communicate the important terms about an idea (or topic). But they also call out attention to writing issues that authors might not realize they have. David Weinberger comments:

"For example, the list of the 100 most frequently used words in my book Small Pieces Loosely Joined begins with "although" and ends with "yet," which reflects my unfortunate tendency towards mealy-mouthedness."

The authoring insights that topic clouds provide is why we include this capability in every blogsite; it's a quality assurance tool. And topic clouds seem to be as important to search engines as they are to humans. Check out this Google footprint for one of our blogsite users:

site:blog.podblaze.com "/topics"

Another interesting project is JetStream - similar in ways to some of the early [experimental] SmartSpace projects we did for Oracle and eWeek - except years before tag clouds became popular.
