Mastiff: I don't mean to pile on here since so many of us are anti-IE (as am I) & you clearly prefer IE.
As recently as a yr. ago Firefox/Mozilla had about 5% of the browser market. Now, the number is closer to 20% & it grows every day. And unless IE 7.0 improves by leaps & bounds & basically works much as Firefox does now then it will continue to lose market share in future.
I agree with you that WP should work properly in IE for the reasons you state (though I hold my nose saying it). But you should imagine the consternation I feel when I visit a website programmed only for the IE user & which looks a mess when displayed in FF. The programmer has created a site that only works w. a single browser & that's annoying.
I think many of us feel that FF is the wave of the future (& present) as far as browsing is concerned. And you make a mistake in dismissing it as only for geeks and technophiles. I don't have much more than intermediate technical skills at best. Yet, I love my FF.
The way one should look at FF is that it does so much more for you than IE, but it doesn't spoon feed you the way IE does. It makes you do some work in installing & configuring the software & maintaining it. But it gives you so much more in return.
WP is in exactly the same relation to blog providers like Blogger.com or Typepad. THe latter do everything for you but provide you so little in return. In return for a little bit of technical work WP provides so much more.
If you're willing to settle for the stripped down version, then perhaps IE or Blogger.com are for you. But if you're looking for more out of life then FF & WP are the ticket.
YOu make the same mistake in saying you wouldn't recommend WP for someone who isn't a geek. It's very easy to do a basic install of WP & use it at a basic level if you don't have sophisticated technical skills. It breaks my heart when I see people settling for blog providers like the ones I listed because they supposedly do everything for you. People who see it that way are selling themselves short & settling for a middling product.
