Blogger will let you post to an email address. That is, you can send an email, and blogger will post it as a post.
Feed my Inbox will let you select RSS feeds and have them sent to your email box.
I bet you can figure out where this is going.
1. Find the RSS of whatever it is that you want to have posted in your blog.
- Facebook RSS can be found here.
- Library Thing RSS is found on the profile page, in the lower right. Just "copy link location".
- left column: Settings
- Mobile & Email
5. Repeat as necessary.
