I'm with sami on this one. You need both, so get some of both and have at it. Over time, you'll get to deeper and deeper layers of technique, but I think that focusing on too much technique too early is a great way to get paralyzed.
I also think that it depends on what you're trying to accomplish. If what you want to do is dance for fun, go dance; don't overthink it. If what you want is to become an effective high-level dance competitor in as short a time as possible, then start with someone who can teach you technique.
I also think that the article makes some great points. I love the lion analogy. Lions naturally do what they need to do. Nobody has to teach them how to align their bodies for proper stalking. they just stalk. I think it's possible that we adult humans may have spent a lot of time laying poor "technique" on top of the good stuff we knew naturally. It's under there somewhere. We've just forgotten it. Example: How much time have we, collectively, spent learning to walk? Just sayin.
