Phoenix. Tons of transplants from SF have moved here already, ASU is nearby, Sky Harbor has tons of flights going to all of the tech hubs in the US, cost of living is affordable and there's a decent amount to do here as well.
We have a tech scene, but I wouldn't consider us a big hub at the moment. Most companies just have support or administrative staff here.
This is very cool research. I would love to see topics like this built into a browser extension (or even into HN itself although that may be beyond the scope of HN's core features). I find that there's a decent bit of content that gets posted on HN that I'm not personally interested in and, on the flip side, there are times when I want to go more in-depth on a topic but can't find more posts that cover it. I don't really want a whole subreddit-style navigation system, so some automatic topic tagging could be a nice middle ground.
