Hey, World
New, in beta, weblog service from HEY where you post by sending an email to world@hey.com.
I was reminded of Blogger Mobile from 2005(!):
When you send an email or MMS to go@blogger.com we set up a new blog for you and post your photo and text to it. You can keep the blog we set up for you or switch everything over to your existing blog by signing in to go.blogger.com with the code we send to your phone.
