I am against comments on Tumblr. Why? Because Tumblr is a site for tumblelogs. The tumblelog is a beautifully simple medium. One of the wonders of the simplicity is the lack of a commenting system. […] Why would you throw all kinds of extra crap onto a medium that exists for it’s simplicity? Wordpress is free. Textpattern is free. Symphony is free. Livejournal is free. Blogger is free. There are so many other platforms to blog with. Why duct tape comments onto a tumblelog?
