you could also say you have no clue how many people are here because of boredom. Or how many people read are terrible anorexic and using all of this as inspiration, if you want to get technical about nonsense.
I was going by the 'DATA' if you will and inferring based on people posting.
I think its commmon sense that I don't all the people here that are reading and not posting and why they are here. Also if the same person views a post 50 times.. its gonna come up as viewed 50 times FYI
