Bad: They only put abbreviated parts of the feed in each post. So you couldn’t read the whole thing in your feedreader, and kept having to click-through to the New York Times to read all the posts.
Worse: All they did for the excepts was take the first X words from the full post. This sucks on its face, but it’s worsened by the writing style of the authors. They tend to start off with something irrelevant, then work around to their point. This means that all that was in the feed was something completely random that got cut off and gave me no indication if I wanted to click-through to read the rest of it.
If you’re going to abbreviate your feed and make people click through, write explicit excerpts that are designed to give your reader the information they need to decide whether or not to click-through.
I’m sad because the blog didn’t live up to the book, largely for nothing but usability reasons. Too bad.
