I find it absolutely ludicrous that some people insist on CC'ing emails to half the planet when they find errors/inconsistencies/etc.. that someone else has made. Especially when these items are very insignificant and the people that they are CC'ing have nothing to do with the problem at hand nor would they benefit from being made aware of it.
This practice is a prevalent cancer on numerous projects that I have been a part of. I must admit that on occasion my ego may have gotten in the way of my judgement and perhaps on rare occasions, I was one of "them". However, from this day forward this is a form of politicking that I refuse to be a part of. Why not just take the issue up with the person(s) that are directly implicated with the issue at hand? I understand that on rare occasions it may become necessary to notify a superior of repetitive incompetence of an individual, but there are professional ways of going about this.
This senseless form of "showboating" has resulted in me loosing respect for some close colleagues. A shame to say the least.
I wonder how many people can actually see the "true" nature of these emails. I am going to coin this form of emailing BB'ing (Bullshit Broadcasting). I must give credit to a confident for the term broadcasting in this context, but I will not mention his name. So if you are someone that participates in BB'ing, do us all a favor and give it up!
Life is not a "Big Dick" contest!
