As silly as it sounds, if you are a senior developer/eng director that is in high demand these days, the product that you'd be working on matters tremendously. Having people motivated by the whole of the product they are working on is huge, while individual complex problems are also fun, staying power lasts in people who want to use what they are building every day.

I think the sentiment of this article is more around finding senior developers who are also interested in the product you are building. Which is a huge problem because the intersection there is even more sparse than finding a senior developer that just wants to solve generic, complex problems.

I was about to say, isn't this site a year or more old? It's been the same colors for a while now.
