I use posterous. It's awesome! You send an email to post@posterous.com and you have a new blog! You don't even have to sign up- you can leave it like that and every time you send an email from the same address, it automatically goes to the same blog! You can simply 'attach' a file to an email and then, it'll send you a message letting you know they got it- and you'll also get a link to the blogpost. Also, there's supposed to be some way you can 'update' your other sites from your posterous blog- I'm sure you'll have to sign up then.
Here's my posterous, if you wanna' see-
http://sharnon007.posterous.com/ThanX for the great games. I'm FINALLY able to figure SOMETHING OUT! When I actually see the results, I'm so proud of myself! and GRATEFUL to you, of course.
