Might not exactly qualify as a "product", but the weekly newsletter they offer has some of the best PM articles, books, & resources I've found anywhere. Here's an archive of all the past weeks - http://us7.campaign-archive1.com....
@bcheng42 Absolutely! I thought the handbook was an awesome read - great interviews; and I check out the links / book recommendations in the newsletter every week. Thanks for the resources!
@UXAndrew Hmm that's strange. Check your spam folder? There should be a confirmation email from mailchimp and then the next email should include the handbook.
