Dogfooding your product is not enough
You should use the product you are building, yes? It seems obvious but there is a bit of nuance to this process.
While building Corgea, we try to use our own product as much as possible. We use its core functionalities and its integrated into a normal flow.
The other day I was using Corgea to accomplish a very specific task. There was a different intent around my usage and brought a new perspective that I hadn't experienced before.
Then it dawned on me, simply dogfooding is not enough. Use your product with the intent of accomplishing something outside the product itself. You will get a whole new perspective on the experience and what to optimize for.
