Google that! You´ll find many different responses. I started writing code in note pad to make one of the first web pages that ever existed on the world wide web back in 1995. Things have really changed since then. Now almost 20 percent of web pages are developed in WordPress. Of course, being a web design tutor I always have to stay ahead of the game.
Web stuff comes and web stuff goes. Remember American On Line? I have a friend that had $250,000 dollars worth of that stock, and one day it was worth 5 dollars. Poof!!!!! Gone! I´m thinking the same will happen with Facebook.
Anyway, I don´t think that Adobe Dreamweaver is dead. I think that the way that Dreamweaver will be used is changing. I use Dreamweaver everyday to edit WordPress themes, plugins and widgets. It´s a great code editor.
The great thing about understanding Dreamweaver as a web designer is that you have to understand web basics like html5, css3, some javascript and some php (some mySql helps too). Dreamweaver lets you do all of that and see and manipulate the code.
While for the novice hairdresser that whats to put up a site with some pictures, a calender, a contact us form and an address, understanding just enough WordPress to get by is an OK think.
But when you´re a web designer, you live in a world with Billions of web sites. You clients and potential clients are coming to you with all kinds of wants and needs. Some of these clients will have existing web sites, some will want to create brand new ones. Either way, having a firm understanding of site structure, html, css and the relationships of code and files in any site is something that Dreamweaver reveals very quickly.
I use the Adobe Creative Cloud. I pay $50 a month to use Illustrator, Photoshop, Audition, Edge, Flash, Dreamweaver and other stuff in the package, and it is always being updated. I works for me.
But all things change.
