What's a Widget?

In all honesty, I'm not very computer savvy, but I've managed to incorporate widgets into my blog. What's a widget? Well, just look to the right of this post, and you will see my very first widget. It allows me to promote author's novel covers and include links for visitors to find out more of what the novels are about and how to purchase them. I'm finding that widgets are a crucial part to every author's blog site :) Happy writing!
