I've been experimenting with the posterous.com blog service, a really simple solution for blogging that I learned about on Guy Kawasaki's blog . I've set it up so that blogs posted to jtchatter.posterous.com will automatically be posted to my other blog address, jtchatter.blogspot.com.
You can also set up posterous.com to automatically send its postings to Twitter, Flikr, Tumblr, or almost any other mainstream blog service.
If you choose to have posts relayed to Twitter, the first 130 words are posted on Twitter, and a URL links to the complete blog.
