Ask HN: Which articles/blogs should I assign to my high school class?

I started teaching at a charter school recently. Since the school digs my style, I try to push the curriculum by inserting entrepreneurial ideas every now and then.

One of the things I'm doing is to get them into some real-world writings (everything other than English literature.) If I can get them excited about reading blogs and articles online, that will be a good start. So far I thought, this will be a good first essay to read.

Please throw me more suggestions.
