User:Sj/Log/Office space

There's little point in having whiteboards if they aren't regularly erased and reused; and little point in having great open office space if that too is unused and people hang out in small spaces without interacting. Ditto for pubs and dance halls. What is it about great parties and spaces that make them switch from using 20% of their potential to using 80%? Perhaps the same could be asked of great people...
