Scrobbler

Florian’s Scrobbler plugin features a widget that displays your music listening stats in your sidebar. To keep up with your current playlist, it uses AJAX to get updates without reloading the page.

Live Search

Some themes include a Live Search box that uses AJAX to get results fast. Now here’s a widget for adding Live Search to any widget-enabled theme.

Gabbly

A clever widget for adding a Gabbly chat box to your site.

Chitika eMiniMalls

Chitika, a very popular service that helps you make money from your blog, has completed their eMiniMalls Sidebar Widget plugin for WordPress. The eMiniMall is a slick, interactive shopping kiosk embedded into your website.

I don't usually try every widget that comes across my desk but I had to take this one for a test drive. It's quite a treat for me, especially after writing all of the simple widgets that come with the plugin, to see a widget so rich with features. It's a multi-widget so you can have up to nine of them. The pop-up control panel lets you choose from several sizes and set up your own colors so that your widget fits beautifully with any theme. It has an Advanced mode for setting up keyword-based ad filtering and an AJAX form for testing your keywords without leaving the widget control panel. This is good stuff.

To use it, you first have to sign up for a Chitika affiliate account. (That's our signup referral link. Thanks for clicking!) After you receive your associate ID, download and activate the Chitika widget plugin to enable the widget. Enter your ID in the widget's control panel and you're on your way.

Associative Dictionary

What a wonderful toy! This widget sets up a database table that holds user-contributed definitions for words. The widget displays a word and its definition, hyperlinking each word in the definition to that word’s own definition. If a word is undefined, it instead links to a form that allows the user to define the word. I can see this being a ton of fun.

The demo is Dutch. The first person to set this up for English or any other language should leave a link here in the comments!

Democracy

For a great polling widget, here is a plugin to widgetize Democracy.  This requires Andrew Sutherland’s excellent Democracy plugin.

e-Commerce Lite

Instinct Entertainment updates their shopping cart plugin with widget support.

The demo wasn't running superbly when I checked it out but this has a LOT of promise.

Binary Blue

Carsten Albrecht updated his Binary Blue theme to work with widgets. He really went the extra mile:

Full Sidebar Widgets support, including tons of theme-special widgets, including livesearch, authorinfo box and stuff. I strongly suggest to download and use this, as it is a quantum leap in blog customization!
