Gil Penchina is the CEO of Wikia, defined as “a community destination supporting the creation and development of over 3,000 wiki communities for any topic people are passionate about.” And what is Penchina’s passion? “Sadly, mine is frequent flyer miles. I was documenting all the ways you could get frequent flyer miles, all the different credit card offers, and all the other kooky ways you can get them. I have six and a half million frequent flyer miles. I am obsessed, clearly. I can talk about it for an hour at a cocktail party,” reports PC Dan Nystedt, IDG News Service.

And does Penchina have enough miles? “No. I’ll never have enough miles. I have enough miles now that I can fly around the world 26 times, yet I am completely obsessed. That’s what you realize when you run a site like this. Everybody is passionate about something. It’s also fun to be an expert. It’s nice to have people come to you for advice.”
