A fraternity brother sent me a link to Coastr. I just signed up for an account and have to say that I think this concept has some potential. In fact I think this may have been what I was orginally thinking about for BeerBloggers.com, without realizing it. Of course BeerBloggers.com was intended to have longer content pieces and few authors, so maybe not. Nevertheless, Coastr looks promising. I highly recommend checking it out.
