This is very interesting. We didn't want to post to wall because I personally don't like posting much up there but obviously, if we did, its more content for us and some people wouldn't mind. So I agree, maybe that option should be provided. I like the idea of email notifications but we are worried about spam. This is something we struggle with everyday in our brainstorming sessions. Thanks for the points! :)
