The FEEDJIT visitor monitoring system will allow you to track your visitors live and get statistics about where the are located, what page refered them to you and what they liked looking at while on your site.
Although some log management systems provide tracking of users and even live monitoring the best feature of this service is that it does not require you to manage the software yourself.
If you are on a hosted site such as www.wordpress.com or Blogger then you simply install the code on your page and view the results by going to the FEEDJIT website.
Free Widgets are also available for many bloging formats that allow you to view your traffic in a sidebar widget on your site.
