I've read around a bit online and I came upon an interesting topic about automating the creation and management of tumblr blogs. The person would find some potentially interesting niche, quickly create an account, and proceeded to upload relevant pictures from other blogs. He did this manually every day, but I could easily see this process getting automated. He then added his choice of ad revenue, and let the potential clicks flow in. The more blogs he had up and running, and more (although slight) clicks he would get? Thoughts on this? Is it viable if done properly?
