This is one of my favorite Twitter badges, and really simple to create. Just enter your Twitter username on the widget's website (Widgetbox) and then click the button to get code. Great Twitter-like style. This one is showing Bloglue's Twits.

This may not have value to you if you do not read Japanese, but this widget does introduce us to the various Japanese bookmarking sites. Each icon is a link to another social bookmarking site. If you have an account, you just log in and can directly post a link to your website. The code is easy to spot on the webpage.

Another social bookmarking widget that allows you to post a link directly to several Japanese social bookmarking sites and RSS readers. However, Japanese reading skills and accounts in these services required. Code is on widget webpage.
