I moved to Columbus from Portland this past year so I'll throw in my two cents.
"1. Columbus is changing."
When I got here in June, it was the first time I had been here in nearly 12 years and many changes were evident. From a burgeoning art scene to tackling issues of downtown redevelopment to growing bicycle and environmental movements, good things are happening here. It's still a long way from Portland, but keep in mind that people who move to Portland believe in the idea of Portland. As you may have noticed, Columbus doesn't always have that luxury. Another thing I've noticed--and a reason this wonderful city truly benefits from new blood--is Columbus is hesitant to try new things; the powers that be like to see how things work elsewhere and then spend years trying to figure out if a successful model could be adapted for central Ohio. Columbus is generally open-minded, but that stems from a conservative foundation. With that said, I live in the Short North area and am amazed how often I think to myself, "that reminds me of Portland."
"2. We don't eat meat, but it looks like that really isn't much of an issue in Columbus."
I am a predominately vegan vegetarian and have never had a problem feeding myself here.

"3. Unemployment is lower in Columbus than elsewhere in Ohio."
I can't give you specifics on the graphic design market here--though, anecdotally, it seems fairly strong--but I can tell you that after over a year of unemployment (much of that spent struggling in Portland's insanely bad job market) and a cross country Great Recession Migration, Columbus is where I found a job.
"4. Columbus is expanding its public transport system."
The city currently relies on buses, the major lines of which are generally convenient and frequent. If you are involved with OSU there are free shuttles and monthly bus pass perks. Mayor Coleman supports a streetcar line though it's been out of the news for quite some time. Apparently there are still light rail studies on the table, but that's all years away. My hope is that when the 3-C passenger line is up and running in a few years (fingers crossed) it will spark interest among the hesitant (see my response to #1) in finally bringing light rail to America's 16th largest city. I have a car, but it's battery is always dying on me as I rarely use it. I walk to work, walk to campus, walk to the market. I love my car and use it as needed, but I refuse to be car-dependent. Columbus is also making great strides in its promotion of two-wheeled transportation and was recently ranked as a bronze level Bicycle Friendly Community by the League of American Bicyclists; the first city in Ohio to be so ranked.
"5. Columbus is home to a diverse population and its people are open to new ideas."
Columbus is not Chicago in terms of diversity, though it's far more diverse than Portland. A lot of the diversity we do have comes from OSU as well as some of the larger employers. My little posse at work includes a gay Hispanic man, a woman from South Africa (she sounds like Mary Poppins), and an Asian-American whose mother runs a Vietnamese bakery. So we're not Chicago, but we're far more diverse than other areas of the Midwest.
"Ok...so is that crazy? A stretch? Or are we on to something?"
I don't think it's crazy and not all that much of a stretch. Columbus has a long way to go, but it also has amazing potential. What Columbus really needs is more people to believe in that potential instead of complaining about how it's not this place or that place or whatnot. Be the change you envision. When you visit, as you're wandering around the city, getting to know this place for yourself, be aware of the pockets of wow. I run into them all the time and I wish the naysayers would open their eyes to them a bit more. It's those moments when you catch yourself thinking, "Why don't you here about Columbus more? This place is pretty damn cool!"
Feel free to PM me with any thoughts, questions, or just to say hi. And good luck on your journey!
