Ok, this has absolutely nothing to do with science fiction. But it’s fun, so I’m sharing it anyway. UpDown is a site where you get a fake $1 million dollar trading account to try your hand at the stock market. The site tracks real-time prices so you can pretend you’re a real daytrader or whatever you want to be, with no risk to you. And if you’re good at it you can win contests on the site that pay actual money as the prizes. So I’m adding a link to UpDown to my site for a while. Go try it!
