I know that for me, posting via email is an attractive option to make posting to web 2.0s easier and more life-like. After a ton of research, I built a list of web 2.0s that offered post via email. After testing, weeding out paid services, I ended up with... 3. tumblr, blogger (blogspot) and wordpress.com Livejournal offers it but it did not work. At all. For me, at least. So, if you like post via email, there ya go. Hope this helps. Feel free to add more 2.0s that offer this for free.
