I am yet to see a publishing platform that is simpler than posterous. With a single email message containing normal text you create your personal blog and make your first post. No signup, no email commands, no hassles. It’s that unbelievably simple. I didn’t believe it when I heard, so I had to give it a try. Check out my posterous blog.
Once you have a blog on posterous, you can simply and easily change the subdomain name, title, and other site and author info. None of the info are required – fill out as much or as little as you like. It’d be interesting to see who takes over the service first: real users or spammers.
