It should come as no surprise to any bitcoin user that there is alot of stigma out there about bitcoin and the people that use it. I recently ran into some of this first hand.
I participate in a multitude of different forums, and today decided to try and get some users interested in bitcoin. I created a new thread and advertised that I would send anyone who adopted the currency (just downloading the client) a free 0.01 BTC. I provided all proper links to documentation, and quotations to explain what bitcoin is. My post was met with dismissal and accusations of advertising a scam. A moderator even posted that "This is little to no different than a chain letter or pyramid scheme. Those get permanent bans. Are you SURE that you want to advertise it?". His non-obligatory posted warning was generous, and I commend him for doing so (tho I couldn't make use of it because I left to check the temperatures of my rig after posting the thread).
I have been a member of said forum for over 4 years, and I was given a permanent ban. It took 6 volleys back and forth between the moderator and I in private messages to have the ban reduced.
My point, look at the stigma bitcoin has, "This is little to no different than a chain letter or pyramid scheme". The name has been poisoned, this will have to improve before it can possibly meet mainstream adoption.
