I am shocked at this discussion and believe that Wikimania is already quite well branded considering that it was the name of a highly-successful conference in Frankfurt which received a lot of press and also attracted the scholarly community. Because of this conference, I was able to secure a job as a university researcher developing the WikiWizard (a Java applet which highlights wiki syntax) at the Heilbronn University of Applied Sciences near Stuttgart, Germany.
I think Wikimania is a cool name, just like Wiki, Java and iPod were chosen as names for their corresponding technologies because they sound cool. What are the real reasons for wanting to change the name Wikimania and are they greater than the disadvantages of losing an already branded name?
