Keep your friends close. Keep your co-workers closer. That seemed to be the message of the open office, coworking spaces that have quickly spread across the commercial real estate landscape. But then people realized that sitting at big tables in reverberant rooms with loud and often irritating strangers isn’t necessarily conducive to getting work done. Hence, this from Quartz: Coworking doesn’t mean what it used to: “When a coworking company called Alley opened its first location near Penn Station in in 2011, 90% of the space was filled with open desks that anyone could pay to use. At its most recent location, 90% of the space is filled with dedicated desks and private offices … At WeWork, 90% of space is occupied by private offices that start at $400 per month, according to the company.”
