Good article in WomenEntrepreneur on selecting a work space. It points out one of the key issues when choosing office space - privacy versus community.
Most coworking spaces do a great job of providing community, but privacy is often at a premium. Traditional office suites provide privacy, but often little in the way of community. The same is true for leased offices.
In our interviews of coworking users, we almost always hear about this trade-off. Coworking users tend to love the community and dislike the lack of privacy. In most cases the lack of privacy is not a big issue, but for some it's a reason to use other space.
Of course most coworking facilities provide access to private space. I particularly like the private phone booths that many facilities have. Very retro - Superman would feel at home in many.
Coworking users also tell us that use other spaces - home in particular - when they are looking for privacy. So while most coworking are very happy with this trade-off, it is worth considering as part of a space decision.
