I came across an amazing visual dictionary today. I’m not sure it is completely on the topic of sales and marketing but seems like it could be very useful for developing search engine key words or for brainstorming.
Its a website called Visuwords and it shows word maps in a neural net sort of way. It seems like it could be really useful but if nothing else it is visually very cool. I love the way the words swirl around as they form. Check it out.
