The whole expat experience. It's different, being in Asia (ie. Third world countries). There's tragedy that comes with it. I have friends who nearly died in the rioting in Indonesia back when that happened. I have a friend who died in the tsunami when he went on vacation in Thailand. But there are the good parts. Haggling in markets for clothing and pirated things. Being able to go to bars or clubs without the ID. Learning about different cultures and their languages.
Though, I noticed, on the community's interests, it doesn't include Asia... it's mostly about expats in Europe. Because they're more "cultured"? I don't know, that kind of annoyed me. Sorry, I'm just being frank. There are a lot of us in Asia as well. Jakarta, Tokyo, Beijing, Shanghai, Seoul, Manila, Taipei, etc. All of these places.
Anyway, I hope more people join soon.
