Awesome! This is actually quite useful. I wish this could have happened earlier, but in any case, this makes it easier for groups to actively post more frequently (I tried using Google groups and Ning with group projects, but boy people are lazy).
Sounds nice and dandy, but does it keep the URL architecture in place? If I want to move my blog to a new location, I would want to keep all the base URLs in place: for posts, archives (category and date), for tags, etc etc. Otherwise I loose search engine traffic and inter-connectivity between posts.
I asked them this exact question a couple of weeks ago. Sachin actually answered himself and said they can't maintain old urls for now but are working on it.
I'm guessing their scraping the sites content. From a quick Google search it seems that only very recently has their been an easy way to export your data from Ning? Pretty bad form for a network that has been around so long if that is the case.
You can take any content published on the web and use it as your own… Sure, it's a very good idea to have some kind of verification (like "post this code on the site"? some kind of email verification? or at least send a mail to some contact on the copied site to inform the legitimate owner?), but still… you can just use copy&paste anyway. People are very skilled in it.
I'm wondering about wordpress - especially migrating to posterous from an installed wordpress site (rather than having a site on wordpress.com). One thing that is missing from posterous is the ability to put ads like google adsense...anyone know if this is coming? (I haven't seen any hints on their blogs)
