One of the first things you’ll do when you get your great idea is a domain name search… and experience the disappointment when you find it’s gone. But never fear, this is not the idea-shattering catastrophe it first seems.
This is because your clever name doesn’t matter. There is a seemingly strong counter-argument, that goes “…but, brand is crucial – look at how much all those big companies spend to make you remember their all important name!”. This is true, however before the names existed (outside of their inventors heads), they weren’t special because they weren’t attached to something anyone cared about.
