For a personal blog Posterous is just easier... The only thing holding me back is the lack of themes..... I barely write on my Wordpress blog now (http://chachafance.info) because it's often too much of a hassle. I've tried Tumblr and it's alright but Posterous beats them all in my book for a quick and easy way to keep up a personal blog. Since Posterious makes it easy to host your posterious site on your own domain I guess I might as well go for it.......... Just thinking out loud.
