From my noobie point of view, a coworker has been telling me about Bitcoin for ages now so I finally gave in and sent some money to BTC-e to buy my first Bitcoins. He told me to come here and I will find everything I ever wanted to know about Bitcoin.
I definitely see huge potential for Bitcoin and I am a good example of how word of mouth through friends, family and coworkers will really help Bitcoin spread.
I would have to think it can already be called a success. No telling how much more successful it may get.
