JOG THE WEB is a web-based tool that allows anyone to create a synchronous guide to a series of web sites.
Its step by step approach of taking viewers through web sites allowing the author to annotate and ask guiding questions for each page is unique.
Give it a try and start creating your own Jogs.

New : We have finally found a fix for the Framebuster issue (you know, those pages which systematically made the jog disappear...). A pop-up now warns you that you are about to leave the jog and if you click on "Cancel" the rebellious page displays within the jog and you can move on.
