I'm starting a new very simple site. Without giving away too much, the main goal of the site is for people to be shocked by the images and want to share it with their friends. I'm familiar with wordpress, but I'm also looking into Tumblr right now as it seems to fit my simplistic needs. I will be hosting this domain on my own host. Have any of you used Tumblr? I realize there are many factors to having a viral site, but would you think Tumblr would work best? The majority of visitors will be coming from social media sites and some from SEO. I'd appreciate any advice or suggestions. Thanks and rep will be given.
