Dickeson--Where Does e-Commerce Fit?

Cyberbrokers?
Pre-Internet, we'd have called them print brokers, wouldn't we? Are they still print brokers, now that they operate from "sites" in cyberspace? Do we now call them cyberbrokers? And how do they fit with the service model of commercial printing? Is what they provide simply a print-exchange, a "trading floor," for "bid" and "asked" prices on sets of specifications for printing jobs? Are they useful primarily for the print-as-commodity model? Or is there value above and beyond simply providing a pricing nexus that enhances the print-as-service model? Although their sites are lovely displays of hypertext markup-language technique for the World Wide Web, they lack explicit content that immediately informs us of function. (I'd settle for less dazzle and more information.) Do they charge a commission on each transaction like a cyber stockbroker? Who pays for the brokerage service? Buyer? Seller? Both?
