One aspect of Posterous that tipped the scales for me is their group capabilities. Any site can have multiple authors or contributors – this combined with the ease of posting has given my family sites a whole different type of community where everyone can send in photos and comment on them.

Posterous also sends out the full content of your posts via email so everyone is updated instantly without having to visit your site.

Thanks for a great post – I’ve bookmarked it and will send to my friends the next time they ask!
