I've answered a lot. I've been here since May of last year. So almost a year and a half. Is it curious? Well that doesn't even make sense. Do you mean suspicious? No it's not, I just have a lot of time on my hands and enjoy helping people.
I'm assuming you're thinking of people like Dread Pirate Jackie or Tony737. Well, these are people who are very dedicated to this website and, even though they're incredibly busy, take time out of their schedules to visit this website and commit to helping others that visit this website.
Also, because it's fun and answering a lot of questions makes me feel intelligent.
