User blog:Blinkn/Keeping Secret Identities?

I'm certain I'm not the first to ask but how has Bruce managed to keep his identity secret?

The weak link is not him, his cover is certainly better than Clark's, a damn pair of glasses.

But Bruce has had... three wards and Batman had three separate Robins and then Bruce Wayne finds out he has a son and yet another Robin appears the same age as said boy.

The fact that their have been different young men donning the Robin persona seems common knowledge to people at least in the animation, civilians seem aware that Robin I became Nightwing, Robin II died, etc...

So is this just a matter of suspending disbelief that certainly was the case back when this started in 30s and 40s, simpler times of bat everything even bat-cookies but now what excuses/ rationale were made up to cover up the identity before the whole Batman incorporated business.
