Posterous
Almost anybody knows to send an email, right? 
Then almost anybody can have a blog?
How?! By using Posterous.
You send an email at post@posterous.com and your blog is set up in few seconds.
You adjust the name of your blog (e.g. myname.posterous.com), you set a password and then you keep sending emails to post@posterous.com. Every time when you send an email a new post is inserted. You can format the text with your email client as you like, you can attach files, etc. All things will be uploaded to your blog nicely w/o any extra formating. Of course, there is a web frontend for further management, but the email thing rocks.
So, when you send/forward some fun email, don’t forget to add post@posterous.com in Cc:
