My experience working there for 2 years matches what many co-workers in Houston and Dallas often tell me - Austin may be in Texas but it’s not “Texas”.
I initially laughed at Pittsburgh being in the top 10, having attended undergrad/grad and living here 25+ years, but it’s tough to have any type of “college” feel among 2M+ population.
But having grown up in Columbus, I’d be very hard pressed to explain how Pittsburgh is a better “college town”. It seems to be more just a rating of the cities - great city, just not college-focused.
Given that Orlando is larger than Pittsburgh, Austin, and Las Vegas, and Cincinnati is larger than Austin, some of the classifications are odd.
