I used Dreamweaver when I started out because I didn't know any coding whatsoever.
I then got into the coding and quickly ditched Dreamweaver, partly because my trial had run out and it's very expensive, and partly because it took so long to launch. It also cluttered up my coding.
I started using Notepad, and now use either Notepad or Notepad++.
I really don't like WYSIWYG editors, they have a habit of destroying my web pages by trying to "help" me.
As for what I do, I've edited PHP for an SMF forum I used to run, also websites built with HTML, Javascript and CSS, for my old clan site, my business site, my college work, and any work I can pick up for others.
Aegis - remember that whilst Dreamweaver does offer a realtime preview of the coding, it doesn't always look right - a web browser is still a better option for previewing the pages. Also, watch out for the coding it inserts - it generally needs a lot of cleaning up when the website is not hand coded. But I do think that editing it WYSIWYG style and watching the code is a good way to learn, that's how I started off and it really helped me.
