The photography of Kyle Thompson is a case in point. Earlier in the year, he posted some of his work onto the site and it instantly took off. Within hours it had received over 4 000 000 views and, according to an update this week, within months Kyle Thompson was receiving interest from big publications and seeing his work in magazines. He now works full time as a photographer I believe, and is doing phenomenally well.
I'm no art critic so I'll let his work speak for itself. I was blown away.
