Gnomeaggedon (the one true and original version) posted this on his blog today about a widget that Saresa found that does some analysis of your characters name. It is called the WoW Armory Character Distribution application. It will check the US as well as the EU servers for your name and then make a pretty graph of the breakdown of the characters it finds.
Desdarii still only had three characters found (there are apparently no EU versions of the name yet). What was interesting was that they were all draenei, 2 were female, 2 were mages and 1 was a warrior.
This was good to know but to show a big fancy looking graph I decided instead to look up Goldy, my priest's name. There a total of 164 characters with the name of Goldy.
Goldy is a name I've used for several years starting back when I was playing Dark Age of Camelot. My first character was a druid on the PvP realm is named Goldy and who knows how many alts I created over the years.
