I agree. It's more than just reading code comments, though. Sometimes comments about the article itself can be just as important.

I've seen several MSDN articles marked as incomplete or having bad syntax in the comments that users post to the articles. And sometimes commenters can point out other ways of accomplishing a task, or better performing methods.

But the biggie is when commenters let the article author and the world at large know when a key piece of information is missing from the code. Hence, reading comments can be a good thing when looking for solutions. All comments.
