This tweet became a hot discussion on twitter between Sam, Dave and many others who had something to say. IMHO Sam took a strong stance with his tweets; he probably has a justified reason for doing so. Many subsequent replies gave examples of successful startups that worked at co-working spaces as a counter argument. I would like to know what HN thinks about this. Can a co-working space really be the reason why many incubators don't work? There are a few examples that suggest otherwise; so this may be a not so meaningful pattern that Sam seems to support?
