To the Bat Cave, Robin!
Robin?  Robin? Where are you boy wond……  Oh, for f*@ks sake! get off facebook so we can go and fight crime!!
(That is how I imagine a pretty typical Dynamic Duo conversation would go these days.)

There are millions of Batman fans out there on the internet. Many of them will have smart phones, and may be using any number of a vast array of  geo-location applications.
And I will bet each of them thought they were really cool, ironic and unique when they added “The Bat Cave” as a spot on the map, so they could check-in to it.

Go to pretty much any city, in any geo-location site (such as Gowalla, foursquare or Facebook Places) and you will find multiple entries for “Bat Cave”.
The same holds true for the “Fortress of Solitude”, Hogwarts and Castle Greyskull.

But I could not find anything for the Arrowcave (Green Arrow) or Sanctum Sanctorum (Dr Strange)

Geo-location applications have really taken off in the recent past, but at present they seem to suffer from a major problem.
That problem is letting the general public add your data for you.
When you do that it is a great way to get free data-entry done, but you never know what you will get.
You will need to be happy to have incorrect data, duplicate entries and millions of joke entries.

Although, if I were the kind of person with a secret lair, then right now would be a great time to add it multiple times on geo-location sites. Add it in so many different  locations that the bad-guys will have no idea which is the real location.
Oh, yeah – and I probably would not add in the actual location, just to be on the safe side.
