You may have noticed there is now a Tag Cloud on the right side. This crawls through the labels on the blog and chooses the most often used words. Clicking on any word will bring you to the postings where that label has been used.
It took a great deal of time to find a Tag Cloud that worked well with this template, but I finally did at http://www.wowzio.com.
Additionally, this service has created another interesting service called Pulse. They are in the process of extracting product reviews from blogs that they are hosted on to create consumer product ratings and reviews. From what I could tell, so far, it is limited to some kitchen appliances, but hopefully this will expand as they progress further. Keep you eye on it. These are real reviews by real people who have written a review on their blog about particular products. http://www.wowzio.com/docs/insights-shopping
