Widgets are useful tools. I like the poll tool. It's a way to get feedback from students, parents, or staff about an issue or idea. Keep a poll open for a couple of days and than review the results. There are some interesting counters. The globe on mine is nice for showing 3D flags of the locations of people currently viewing the site. There are so many interactive tools. The key of course is to use the ones that support your purpose for the blog, or entry.
