I came across the import function on Posterous while having a look round to see how things work. Seemed a simple process, type in the web address for your blog, be it WP, Blogger and others, click the button and away it goes. Ten minutes later all my posts had been imported into Posterous. Job done.
It's made a good job of importing as well. Text, images and multimedia has been brought across and ispresented nicely. The only issue I had is that any script from Zemanta is left displayed as text at the bottom of the post.
Aside from that, a job donefrom Posterous.
