I think it's great, what you are trying to do. You have the time and energy to make it. However, as LifeInAsia mentioned, don't let the "I made millions from Google" stuff sway you too much. It's still work and it takes time to pay off. I started an online forum for a niche market at the beginning of the year (in my spare time). So far I think adsense is paying me about $.07 per hour that I work on the site. The $.07 is not taking into account the hosting expenses.
Now I have learned tons of stuff by taking on this project and that is valuable. I've searched jobs in the US using some of this knowledge and they pay fairly well.
My advice is build, learn, repeat. You will eventually get there. And you found webmasterworld, that's a great start.
