This kind of applies to a lot of recreational activities. People become leaders of all kinds of different groups regarding their interests. Skate teams have leaders, sports teams have leaders, people who play in bands have leaders (and the people who organize shows between many different musical acts).

However, all those require actual social interaction and getting out of your house, meaning the skills probably transfer over into a job better.

People playing WoW are sitting on their computer playing a video game. There's no face to face interaction and prerequisite social adeptness. You can be a total hermit and be a WoW guild leader.

So yeah... but no.
