Often I'm asked to explain BTC to someone and occasionally I come up with something stellar that really nails it, but most times it's a rambling incoherent mess.
What I would like to see is a short and simple explanation of what BTC is that is suitable for someone non-technical to understand.
At present, Bitcoin information is quite popular and widely spread on forums, websites, people who do not know Bitcoin can take the time to read articles or study about it easily. I think you do not need to post to ask this question.
