Kai showed me posterous the other day and I signed up yesterday. VoilÃ ! It
allows to post by sending mails to firstname.lastname@example.org. The cool thing
is, it will cross post to your blog, twitter, tumblr and even add photos
to flickr at the same time. If you don't want it to you can control it
by specifying the services in the recipient part of the e-mail address,
e.g. twitter@.. (or combine services by concating them with +). Only
missing service for me is identi.ca.
