All StartUp communities face a common danger: hot air. Hot air is a phenomenon, that describes empty talk that is intended to impress. I call those people idea sellers. Being able to impress and get information across in a captivating way is not bad trait, the problem is when there is nothing behind that.
In contrast, someone who has a good idea, but can’t sell it is also not ideal but not deceptive towards others.
Both extremes are bad and hot air is dangerous. One should have a good idea, product etc. to back big claims up. Therefore, someone who has a great idea and can, furthermore, sell it – is the ideal entrepreneur.
