From the developer:
iWeb to WordPress converts your iWeb blog to a WordPress blog.
With MobileMe being discontinued in less than a year, iWeb blogs will not be able to have commenting or a search feature. Now is the time to convert your iWeb blog posts and comments to a WordPress blog before your comments disappear with MobileMe*.
iWeb to WordPress converts all of your iWeb blog posts and comments so that they can easily be imported into WordPress.
