Goodness, I love your blog theme. It brings back so many memories.

I agree so much with you that I gave a talk at SecondConf several years ago exploring much the same thing. In the end, I came up with a definition for an indie that works at least for me.

I defined an indie as:
A person willing to do whatever it takes to follow their dreams in their own terms.

Reading it now, I realize it probably should have been "person or group of people" oh well...

I feel indies are best defined by what drives them, their passion. If your goal it to make money, perhaps you're more of an entrepreneur? But yeah, if you're trying to make that thing in your head a reality, having a day job, taking VC money, partnering up, etc. are just things you are willing to do to make it happen.
