@jenniferherndon (and others), I think Tumblr was more of what Twitter was supposed to be. Twitter was originally a place to post short thoughts and photos, and it ended up turning into a real-time communication tool. But Tumblr, and Posterous, are both more of that short-form blogging platform.
I have a Posterous blog and a Tumblr blog. Depending on what I’m doing, I’ll sometimes feed my Posterous blog into my Tumblr blog. Other times, I’ll only post to one or the other.
There’s also a small SEO advantage to have your WP blog feed into your Tumblr blog, but it’s a very small one. May not be worth the time to do it. Maybe if you have a work blog and want to keep personal thoughts and interests separate, your Tumblr blog could work for that.
