Internet distribution channels

After googling, but not finding what I was looking for, did it myself: a mindmap of Internet Marketing Mediums (Distribution Channels).

The channels are selected based on Estonian market, therefore it doesn't include the ones not too popular in Estonia.

PS: recent Social Media Marketing Report indicated that "By a long shot, Twitter, blogs, LinkedIn and Facebook were the top four social media tools used by marketers, with Twitter leading the pack."

PPS: lately I've been using twitter more and more.
