Netfishers worked with Third Voice to fix the problem before it could be exploited. July 9, 1999. Javascript imbedded in a note was used to change the content of the web page displayed to the user. The Javascript intercepted the page information retrieved from a web site, and displayed a page that had a different title and first paragraph than the page on the source server. You don't need to post a note to be tracked.
Tracking starts as soon as the user logs in.
The first beta release allowed users to surf and read notes without logging in. The second and third required the users to log in, even just to read notes. Part of the rationale for needing to log in is so Third Voice can track the notes that are being read. Part is to track user's surfing habits. But this one, anticipates Jurvetson, will bring in 100 times greater advertising rates because of the pervasiveness of the medium.
