I heard the founder of this speak. He said he is turning a much higher profit than typical brick-and-mortar businesses. He rents out some of the space very creatively for non-office things as well, such as birthday parties. He is also very active in the community, for instance he hosts freelancer meetups.

Also, note that the neighbors of BlankSpaces "include FedEx Kinko’s, Wells Fargo, Starbucks and Staples."
