Every week, I seem to discover a new tool, plugin or widget that can be used along with Twitter. Most of these are web applications, but take a look to see if there’s one that can help you use Twitter more effectively.

• Twitter Snooze - Puts your Twitter account on vacation for up to 30 days.
• TwitterFox - Adds Twitter to your Firefox browser.
• Twitbin - Another plugin that adds Twitter to your Firefox browser.
• Twubble - Helps you find more people to follow based on who your friends are already following.
• Twhirl - Gives you the ability to follow your friends and update your Twitter status without logging into the web version of Twitter.
• Twitter Tools - A plugin that allows you to add your Twitter updates to your Wordpress. You can even update your Twitter status from your Wordpress admin panel.
• Facebook Twitter Plugin - Your Facebook status is automatically updated with the status from your Twitter page.

Are there any others I should add to this list?
