Now, we all know what coworking is / what coworking spaces and makerspaces are. If not, feel free to have a look at the Coworking Wiki and read about the History of Coworking.
Fun fact: C-base in Berlin (Germany) is considered the first hackerspace and dates back to 1995 - not that overhyped area in the US .
Anyway, "collaborative working" increases interaction and exchange and by that it can lead to new ideas and such - probably THE reasons why it is so popular in the startup/entrepreneurship scene. In that sense, a coworking space should be easy accessible, flexible and encouraging to talk to each other - to build a community.
In Japan we have shared-offices which are mostly located in odd-numbered floors of fancy buildings and very exclusive and closed regarding membership. Not all but many, including some bigger names. They are advertised as coworking spaces but really don't support the mindset behind it that much. However, the Japanese attitude and thinking seems not really to be seeking for that and everyone is fine... without really knowing the potential.
Now, my experience is limited but maybe you had different experiences? How can we change that? Should that change?
