The implicit web is all about the value that will accrue to an Internet user when their every action is tracked, recorded, and used to provide value back to that user. There is also a second order play when that clickstream activity is shared with the user’s permission with everyone else.
This concept can be used in almost any activity you do on the web. Take shopping for example. Amazon does a decent job of capturing the activity in our account and recommending new stuff for us. But we use an aggregated account at Amazon, so the Gotham Gal’s books, Jessica’s music, my gadgets all get lumped into one profile. What if I had a profile of all my web activity and I could express it to any web store the minute I arrived? Amazon could do a much better job of recommending stuff for me. So could eBay. So could Netflix. But take it one step further, connect me to other people who are looking at and buying stuff just like me. Let me see what they are buying and where and why. That’s social shopping in my book.
