I feel like I have pretty good insight on this issue. I actually use both. WordPress is my backend for Tumblr. I run a news blog called ShortFormBlog ( http://shortformblog.tumblr.com/ http://shortformblog.tumblr.com/ ), which has content that works well on Tumblr but requires a more robust approach in terms of the creation of the content due to the fact that the posts tend to be more graphical in nature. Which is where WordPress comes in. It has a lot of benefits. When breaking news happens, I don't have to cover every piece of the story … I can reblog the missing pieces from other news Tumblrs. And if I want to do more detailed posts, I can switch back to my customized WordPress backend, which has a modified version of TinyMCE and Tumblrize to allow me to do more design-heavy posts. I also get to keep an archive of the stuff that took more time so it's held in a non-centralized place. The overall benefit? At 6,000 followers and counting in just six months, I have a much larger audience than I ever did with the WordPress site. There's much more communication with readers, and since it's centralized as opposed to all over the place, it's easier to latch onto. I also have gotten some media coverage from Mashable and Mediaite, and I've even worked with the Tumblr staff on some things. WordPress has its uses, but Tumblr has major advantages that you can't get with a self-hosted site. The community is there and it's been well-nurtured. That's as good a reason as any to give it your attention.
