Personality Type?

I was musing lately after my last perusal of the forum postings....Got me wondering about personality types on here and if there is a common thread. I, myself, am an INTP and I seem to see some parallels with the members of this forum. I am an Engineer and a musician that plays drums. As an Engineer I was quite aware that although collaboration could be fruitful, I was aware that pursuing an idea alone was fruitful as well. I also think that because of my personality, I am fine with being more in the background playing the drums. So then, I am just a bit curious if the members of this forum are more alike than different than the general population?
