This has been the most popular WYSIWYG web editor for quite some time. Still a substantial learning curve involved and it isn't cheap but it is quite a powerful program. There are very few competitors in this market really. Many products have come and gone but nearly ever other web design product requires learning to code in HTML and/or CSS (which really helps anyway).
Develop more web content, more quickly. A streamlined user interface, connected tools, and new visual CSS editing tools let you code efficiently and intuitively.
