I grew up in Fishers, and currently go to Purdue (an hour north). I can say from what I've seen that tech really is coming here, it isn't trying anymore. I know there is a lot of 'Silicon Valley of X', but I don't think Indy is trying to be the next Silicon Valley. It feels like the people here are content at solving problems big and small, and not as focused on capital and business. Personally I think this a good thing, and prefer it. And of course as the article states, a little Midwest politeness pervades the area.
Salaries are also way higher in the area then they used to be (expect maybe $50,000-60,000 in the area, at least for new grads in the area for larger name companies). It's not SV wages, but it's not city living either, and the area is great.
To follow some of the people in the area, I'd look at @DonWettrick [0] on twitter, he's an educator in the area and a lot of his students are a part of Launch Fishers and are coming into the local start up scene. If you care about the next generation, definitely a class to keep up with!
