In my experience, Frontpage is used as a breaking ground for people who want to develop web sites. Like others said above, it does add a lot of code to your web pages, but that is to allow Frontpage to interact with certain parts of your page for future ease of updating, etc.

Most people will shy you away from FrontPage to another program, such as Dreamweaver. If you want a WYSIWYG editor, try using Dreamweaver. I enjoy using it, and it only adds minimal code to your site, if any at all, depending on how you use it.
