A good friend of mine worked for BirchBox, a subscription beauty service for women and men (Birchbox men), as an intern last summer. From what she told me, the work they did to create a community around the service helps the company beat out gorillas such as Amazon. For instance, people will record themselves opening their Birchbox order and post it on Youtube (do a Youtube search, the top unboxing I get has 57,996 views). I think Manpacks also plays to the community, as evident by them tweeting with the fellow who wanted safety razors.
