I've recently been struck by the the office locations at which I've found Boston area startups taking root. And a pattern emerged for me: the center of gravity is along the MBTA Red Line. And there are so many companies it now significantly outweighs the historically-named "128 Corridor."
This shift in the Boston tech scene is so significant that I think we (the Boston tech community) should name this new corridor, and start using the name to bring attention to it. The mere act of doing so can accelerate the reality of it.
