Longmont as a city is great as well. People view it as a cheaper place to live than Boulder, but I'd much rather live here.
Fiber is great, and people forget how much of US infrastructure was communal in early electric buildouts as well.
Some of the objections seems to be reflexive anti-government sentiment. I haven't seen corporate services do well enough to convince me of the realistic improvements. And with most services negotiated on the national level (Netflix, apple, hbo, whatever) as direct buys, the last mile as a subsidy for cable negotiation seems wasteful.
Northern Colorado (Longmont, Ft. Collins) has traditionally been a center for hardware design and test equipment, but unfortunately most of these companies have shrunk overall and have reduced their Colorado presence.
I would say that in recent years the epicenter of startup software jobs in Colorado has shifted back from the brief Boulder startup run and moved into downtown Denver, while Boulder has become a center for corporate outposts (Google, Twitter, Amazon, Microsoft, Workday, NetApp, Splunk).
Commuting from Longmont to Denver is possible but would be a lot of hours driving/on a bus. A rail link is planned but it is scheduled for something ridiculous like 2050 or sometime infinitely far in the future.
