I always like looking at ways to add new user functionality to any web site out there, and Jotabl does provide that. How so?  By the power of Twitter (not to be confused with the power of Greyskull) it gives you a free embeddable shoutbox for your web site.

Once the shoutbox is added to your site, messages can be posted in it two different ways.  Your users can include the URL to the shoutbox in their tweet, and Jotabl will pick this up and place it in your shoutbox.  Users can also leave a message by signing into the box via Twitter, with the option to have the message tweeted for them.

You also can remove message and block certain Twitter users if they get too crazy with the shoutbox postings.  Now Jotabl doesn’t re-invent the Web, however it does provide a neat feedback interface for your users.  Give it a shot shout at jotable.com.
