Great list! I knew most of these sites already, but not all. Def. going to check out the videos of thinktraffic. That’s also why I’m commenting, your links to those three videos are “broken” http://http//thinktraffic.net/derek-halpern-17k-%20%20subscribers-in-11-months – you added a http tag, the links lead to a German game page! :) Just wanted to give you a heads up.
Marketing requires creativity. That creativity can come in many forms. Graphic designers put together visual presentations to attract customers. Writers create content that is designed to engage the reader and keep them interested. A programmer writes code to create a web page that is easy to navigate. Regardless of your marketing role, you need to think creatively.
