Brad Feld, founder of TechStars and a prominent angel investor, was back in Boston and urging local entrepreneurs to sound off a bit more, as the Boston Business Journal’s Kyle Alspach reported.

Alspach wrote that, despite Boston being an “amazing place,” the city doesn’t “pound (its) chest enough” about all the amazing start-ups and companies being built here.

Separately, he weighed in on the struggle that current innovation hubs, like Kendall Square, have as larger companies move in and prices rise, effectively pushing out budget-strapped start-ups.

“This is one of the classic challenges that comes with success of a startup community,” he wrote. “We are having an intense challenge with it right now in Boulder and it’s not at all surprising to me that it’s happening (again) in Kendall Square.”

But even given those challenges, Feld is upbeat on Cambridge’s entrepreneurial prospects. In a blog post last January, he wrote:

The few square miles in Cambridge around MIT is the white hot center of startup activity in the region. One of my basic principles of startup communities is the need for what I call entrepreneurial population density (EPD) which I calculate as the total number of entrepreneurs and employees of entrepreneurial companies divided by the total number of all employees in a region. Then an even more powerful metric is entrepreneurial density, which is EPD / size of region. A large EPD in a small physical region wins.

What do you think? Do Boston and Cambridge do enough boosterism for their start-up communities? And should the two cities think of themselves, like Feld suggests, as related but distinct start-up communities?
