Who is Blackbird Development Group? I was quite surprised that I couldn't find any reference to them on the web. Who, in this day and age, does not exist even if by reference, on the web? Well, apparently Blackbird Development Group. A new start up? A project within a larger company? A secret government unit?
But at least we know that they exist - because while they care enough about their privacy/security to issue temporary security badges to their visitors (with holograms, no less!), they don't actually care about collecting them when they leave. I, not the most observant of people, found this one at "an undisclosed location" ;-).
So, Blackbird Development Group, whoever you are, be more careful next time :-)
