I just wanted to mention a new site, Gabcast (http://www.gabcast.com) that allows you to post audio content directly to your LiveJournal blog (using the Blogger API). Use it to post audio journal entries to LiveJournal when there's nary a computer around. That would've been great when I was travelling the backroads of Laos or Nepal. :-)
When you sign up, select LiveJournal as your blog website, enter your LiveJournal username and password, and then whenever you create and publish a new episode using Gabcast, it will automagically update your LiveJournal blog, with a link to the mp3 file.
