It's not quite as awesome as if Youtube weren't GFWed (or if a VPN actually works on your computer), but at least you CAN start watching what your friends from the rest of the world are sending you.

Youtube并不是GFWed(或是在你的电脑里运行的VPN)那样棒，但至少你是能够开始观看在世界其他地方的朋友正在传给你的视频了。

You're not going to start for the rest of your life if you ever need to solve a problem with a computer from scratch, odds are you're going to reach for some off the shelf packages or libraries or tools that other people wrote so that people like us don't have to reinvent the wheel again and again.

如果你想用Scratch来解决问题,却使用其他人写的程序,或者利用现成的资料或工具,这样以来,我们的确可以避免做重复性的工作,但却永远学不会编程。
