I've made a blidget (blog widget) for this blog and you can see it way down at the end of the sidebar. I used widgetbox, which is a directory of web widgets for WordPress, TypePad, MySpace and other blogs and web pages. It was very easy to use.
There are heaps of widgets available to subscribe to and put on your own blog:
- mortgage calculators
- bookmarkers for any social bookmarking service
- best StarWars characters
- Skype status
- Google calendar
and many more.
