If you are interested in which plugins and widgets are in use on this site, they are listed below. As I add new ones, I will update this post.
Askimet: This plugin comes with the WordPress installation but you do have to activate it and go to their website to obtain an API key. It is well worth it as it keeps your “comment spam” under control! 
JetPack: This also comes with the WordPress installation. This plugin has several different features and you do have to sign up at WordPress.com in order to activate the features but you do not have to host your blog there, just sign up. I use the Twitter widget and the Sharedaddy widget.
Theme Switcher by Ryan Boren is a lifesaver! If you intend to allow your users to switch to different themes on your site whether it be just to give them a choice or to preview themes you are giving away or selling, this is the plugin to do it.
Adsense Made Easy by Cody J Tooker is just that, a simple adsense plugin that allows you to insert your publisher ID, select the size, type and placement of your Adsense Advertisements on your site. A must have.
Tweet This by Richard X Thripp is a plugin that automatically inserts a Tweet This button at the bottom of each post so that your visitors can have a convenient quick way to post your goodies to their Twitter accounts.
My Custom Widgets by Janek Niefeldt is a wonderful plugin that allows you to create just about any kind of html coded widget you can think of. I use this to create and hold my site advertisements.
