If you're not a 'professional' web designer, i see no point in you learning HTML, and if you are you should only use WYSIWYG editors when the boss says, "I need a new webpage in 5 min."

In my opinion, handcoding is meant for 'template driven' sites. You just design your template, optimize your code, and populate the template with content in its reserved spot.

Anyway most WYSIWYG editors have the option to edit the actual html source, and control any and all comment that get automatically generated.

The real power of WYSiWYG editors is automation. For example, if you have a 'template driven' site with some 500 odd pages, DREAMWEAVER or FRONTPAGE will let you change the TEMPLATE and update every page accordingly and automatically.
