Reading a feature-length article (several thousand words long) is one of the peculiar pleasures of life. Now there's a couple of websites that are devoted exclusively to finding the best works in this format and aggregating them. Thanks to Sullivan, I came across this Slate article about a pair of guys called Linsky and Lammer who have set up a website called longform.org. It seems to be jampacked with articles of great deliciousness. Equally useful is another site called givemesomethingtoread.com.
The World Wide Web - it's a beautiful thing.
P.S. The best magazine articles ever.
P.P.S. Conor F is also a longform junkie and has some very good links here. His favourite is John McPhee.
