Put another way, once you come upon what appears to be a legit startup idea, what steps do you take (in order)?
For instance, do you first scour the market for similar startups? Do you ask friends what they think, or whether or not your idea is technically feasible?
What's your process?
It's hard for me to otherwise filter out these uninspiring ideas, because when I first have them, I'm inherently biased. I tend to be in love with the idea that I thought of something novel, and it's difficult to distinguish between that excitement and excitement for the idea itself.
