What do you think about this Social Site idea?

[Louise]

Hello! I’m in Year 8, and recently I’ve been thinking about what I want to do when I’m older. I want to work with computers, [I’m not a geek >.<] but I don’t know WHAT to work with within the computer industry. Basically, I want to do something fun, that pays quite good money. My dad suggested that social networking sites are where it’s at, I mean, look at Mark Zuckerberg, he’s rich! So I want to make a social site, but facebook covers that pretty well. So I decided that it could be like facebook, in that it’s a flat social site, but with a built in game element, so like habbo.com. You can use it normally like facebook, but you can open it up into a 3D virtual world. It could have different types, i.e. for kids, so then kids can get involved in it as well as adults.
Basically, I haven’t made it yet, and it will probably cost a LOT of money, which neither my family or I have, so I was just wondering if A) you guys thought it was a good idea, B) You’d be interested, C) your opinions on it and finally D) what you’d look for in a social networking site that would make you join and stay and use regularly?
Thanks for your feedback!
