I don't see Tumblr get many 'shout outs' here. However I run a Tumblr blog in my niche which has around 2,000 followers. With each post I can get about 500 hits on my blog. Manage to convert some to sales as well. Takes about 20 minutes on Tumblr a day finding things to blog (generally images) and then sending a post out. Some of these images are getting shared around 3-4,000 times which is a lot of exposure. I was just wondering if anybody else uses tumblr in this way? and more importantly, if you don't, why not?
