I'm with Dan. I detest non-standard and proprietary formats being imposed on data storage and transmission. I am text-oriented person. Much has been said and written about how generations weaned on TV, videos, and computer games cognate information in radically different way than did their parents and grandparents who were brought up reading text from books. However, the Internet represents something of a renaissance of text in popular culture, since it has traditionally been mostly text-based, especially in the beginning.
Visual imagery can never convey profundity and depth in the way that text can.
However, of late there has been a slippage toward more reliance on graphics and pictures, and indeed if you try browsing with the pictures turned off, you will encounter many Web sites with nothing showing but some graphics placeholders. On some pages, even text content is presented in graphics. I believe that this is a regressive trend that ill-serves not only the page visitor, but also often the interests of the page owner, especially if the latter is attempting to sell or promote something. When I'm trolling for information on the Web, I'm more often than not use a speedy, text only browser. If I hit a page with no useful text information, I may or may not be motivated to switch to a standard browser to see what they're in frames or graphics.
