Posterbee is a new web application that basically lets you very easily create your own private social network.
In many ways, I think it’s similar to Posterous’ new “Groups” feature — you can add content to it several ways, including directly or via email.
I think Posterbee has a nicer design though. In addition, when you add a link, it just shows you the key content in the link without anything extraneous, including leaving out the ads.
I’m adding it to Not “The Best,” But “A List” Of Social Network Sites.
