I can't quite agree with the verdict on iWeb - or well, I can. Yes, it's extremely inflexible, it produces terrible URLs, etc. But does that automatically mean that everybody who knows how to make a web sites will be turned off?
Not so! I used to hand-code my site. In 1995. I know how to. But do I want to? NO! I gave up on my website because it just ate up too much of my time.
I admire iWeb. I don't care how inflexible it is. Ten minutes is all it takes to get anyone from idea to website. Beat that!
