Widgets are like snippets of code. You can have lots of widgets that do lots of different things.
For example, on several of the MT powered sites that I manage I use the widgets to handle my Google Adsense and other affiliate banners / buttons.
By using a widget to hold the code I can achieve several things:
- The widget is self-contained, so if I need to update the code I don't have to poke through lots of different templates - I just update it in one place
- You can move the widgets around ie. decide which one displays first in a widget set
- You can remove a feature by simply removing the widget from its parent set
They're handy!
