The way Valve is run they are very willing to do seemingly selfless things that promote goodwill and reputation in the long run. For instance, they distributed that relatively polished game alien swarm for free simply to promote Steam. In the case of TF2, I'm betting that their revenue stream actually picked up from it going F2P due to the micro transaction they've go going, but overall I wouldn't be surprised to see them make Source open.
I'm already a fairly fast typer, and I don't look at the keyboard at all when typing. I'm just looking for a way to get much faster than the average, as much for the novelty as the practicality. Thanks anyways guys.
Education doesn't need more funding, it needs to work smarter. I know that's a cliche and usually a lame excuse, but it really does apply in this case. The US spends more per head than any other developed nation, it doesn't need more money thrown at it.
