Adding cool widgets to your blog can be a really good way to keep visitors spend more time on your blog. Visitors who visit your blog regularly usually like to comment below the posts but new visitors usually don't care. But even they don't mind posting a shout in the shoutbox especially when it can be done instantly. They often like to see the response and often come back to your site. You can get a free shoutbox widget at Shoutmix.com.

I liked it because of its simplicity and also its customizable design. You can customize your shoutbox and make it fit in your blog space very well. Look at the upper right hand side of my blog to see the shoutbox. Try it out, you will definitely like it.
