This week, Google launched a new project that it is calling "Screenwise." Screenwise is an attempt from Google to learn how people browse and use the Internet, and the information collected will be used to improve Google products and services. To begin with Screenwise, you must download a Google Chrome extension that will track the websites you visit and how you interact with them. 

As a bit of a thank you, Google is offering anyone who participates in the program up to $25 in Amazon.com gift cards ($5 initially, and $5 for every three months you continue to use the extension). 

The company notes that users who participate in the project must be older than 13, have a Google Account, and use Google Chrome.
