An excellent point Kappacino, we can never be too careful.Having said this I think there are times when it can be helpful to reveal certain details. My background in banking for instance tends to reassure some users I have a grasp of the fundamentals of the law of supply and demand when it comes to Bitcoins. There are 1.2 Million finance workers in my area of the UK alone so I feel fairly safe.As you say it's also when you reveal things like you graduated from Trinity College in Dublin, are left handed and injured yourself in an Archery contest three years ago that the noose begins to tighten around your neck... :-DV.
