It's no secret that we at ReadWriteWeb have a lot of love for startups that make their homes outside Silicon Valley and the Bay Area.

Over the last year, we decided to make a few videos spotlighting some unique, unexpected locations where startups thrive, where tech scenes are vibrant, where cooperation outstrips competition, and where creativity runs rampant. One of the first cities we'd like to introduce you to is home to between 150 and 170 startups as well as a thriving entrepreneurial and creative community. Welcome to Boulder, Colorado.

Editor's note: This story is part of a series we call Redux, where we'll re-publish some of our best posts of 2009. As we look back at the year - and ahead to what next year holds - we think these are the stories that deserve a second glance. It's not just a best-of list, it's also a collection of posts that examine the fundamental issues that continue to shape the Web. We hope you enjoy reading them again and we look forward to bringing you more Web products and trends analysis in 2010. Happy holidays from Team ReadWriteWeb!

With the startup accelerator program at TechStars acting as a lightning rod, this area has grown from an earthy university town to a true hotbed of innovation. In certain parts of downtown, you can't throw a rock without hitting some startup's offices, and I could barely walk three blocks without bumping into at least one entrepreneur, developer, or designer working at a company such as Threadless or AOL.

We interviewed a couple of local startup advisors and one startup team about the culture and community in Boulder. Watch and listen to what they have to say; there are more than a few reasons tech-minded residents love this gorgeous mountain town.
