Wait, what? “Most” by percentage of people who operate at least one website, or by percentage of websites that are “bad”? The latter maaaybe, given auto-generated web spam (“words-with-seven-letters-and-2-ms.html”)?
But to the extent some hotels, airlines, retailers, etc, decide they don’t want my agent and will only sell to me if I personally drive the web browser… sorry, my agent will shop elsewhere.
Economics change, since an agent can comparison shop exhaustively in a way I can’t, but at the end of the day I expect the accountants device that any sale is better than no sale.
