At home, the distraction is being separated from each other. In other spaces, the distraction is another company's non-hackers doing whatever it is they do (loudly). The recent HN link to "open floor plans must die" is spot on.
We'd love to follow Joel's old advice (http://www.joelonsoftware.com/articles/OfficeNewYork.html), but we don't have the time to find and build out an office from its skeleton. We're hacking towards deadlines.
After conversations with brokers and small biz owners, it's obvious the commercial real estate game is just as broken, if not more, than the residential one. I think in an ideal world, we'd just rent a residential loft and hope no one minded half a dozen folks hacking there instead of sleeping.
Have you gone through this? Do you have any ideas or leads?
