It's an online community so it's far convenient to do any work there than at a walmart or other places. Plus, you're not working on the game, you're simply helping the community whether by answering questions, handling violations and similar to keep the place enjoyable for everyone, creating guides to help players, running contests to increase the general activity, or testing for issues to ensure a smooth gameplay for everyone. This includes yourself as well.
Dunno, I've spent the last 9 years (almost half my own years

) involved in online communities and I feel it has helped me greatly --- you learn the language better (english is my second language) because of the communication, you're involved with a game/website you enjoy in the first place, and you're helping out a community to grow. It's a good experience, and even though the job is thankless for the most part, those few 'thank you' notes of appreciation warm your heart. Positions of that type aren't for everyone, including those with too much free time on their hands, it's not healthy to get too involved (not because it's not a paid position, but because you shouldn't make a job out of it, you're still just helping out and not running the place, when it stops being enjoyable and it turns into a chore or a serious obligation then it may be best to take a step back).
