(Last week we talked Webmastery from fandom to job search. Now let's move on to Networking . . .)
Fandom is a fantastic place for an active Networker. You develop your networking skills. You learn to use tools that are good for networking, like Twitter and Facebook. You meet a lot of interesting people. Even a dedicated introvert can become a great networker in fandom.
If you're on the job search, then the networking skills and opportunities you get in fandom are things you're going to want to leverage.
