When I first signed up for Tumblr, I tried to figure out how to cross-post my blog there. It turned out, it was a massive pain in the aardvark. So I gave up. I wanted my posts to be in both places, but I certainly didn't want to cross-post my Tumblr to my Blog, because most of my Tumblr posts are reblogs of amusing gifs. My posts here are usually longer, and more thought out, or at least contain more of my personal opinions. There's a pretty big separation between my sense of the most appropriate posts for my blog, and the most appropriate posts for my Tumblr.
But there's a big category in the middle, of things I would always cross-post, if it were easy -- mostly, big, long posts that relate intimately to some fandom or another -- posts about the Lizzie Bennet Diaries, thoughts on a Vlogbrothers video, responses to Adventure Time episodes. Some of the remainder are more personal posts, that seem like they ought to be on my blog, but kind of belong on Tumblr more than here.
What usually happens is I don't end up writing those posts.
But now there's an automatic Tumblr publicize setting, and this post is, in part, a test to see how the hell that works.
Here's an image, just so I have a clear idea of what's going to happen:
