There's nobody really working on promoting or marketing Bitcoin or trying to educate consumers of Bitcoin's utility. This inaction at expanding the userbase could arguably be the result of the free riding syndrome among the wealthiest holders.
There are more than enough people spreading information on Bitcoin, daily. Word of mouth ^Smile^
I am only one of thousands of people doing it. Person to person
We use forums and websites and youtube to educate people. ^Grin^
What about bitcoin payment processors? Their business is dependent on getting more merchants accepting bitcoin.
