The hypertext and search engine bot has broadened my knowledge just the way agood librarian might. I'd not search for nor seemingly want until I try to determine the link between my search, which represents my limited knowledge, and what I receive. I love that about this bot search stuff because it does bring me relevant stuff I would not have gotten from the very good librarian.
Hypertext comes in many sizes and shapes.
The hypertext I write and the stuff of Amazon are the same.
