Trexy Follows Others Searches

Are you smarter than the average searcher? Search engine enhancement Trexy lets you compare your searches with others and keep a record of your travels.

Trexy watches your searches on Google et al, and allows you to save your search paths for later use. You can also share your searches with others, as well as learn from others' adventures.

Since you can use bookmarks, Google's advanced search or your browsing history to re-find information, the community aspect is the only new hook. But for me, the trail doesn't matter, it's the end result of finding what you wanted. Am I missing something?
