TrackThePack is gone. Seriously.
Nearly 7 years ago, a product that started as me scratching my own itch for a toy business I was running, turned in to an incredibly useful tool that touched the internet lives of ten's of thousands of users and millions of packages. Unfortunately, the economics of it all just didn't add up for us from a business perspective (you can read all the juicy details in a more in-depth postmortem), and so TrackThePack has shut down.
A couple of alternatives I've been suggesting to folks are Slice and Fara.
I appreciate all of you giving TrackThePack a go over the years and taking the time to use it. You're all awesome. And I love you.
If you're bored, I've got my hand in a number of other projects that you may find interesting...or mind-numbing: Baremetrics (analytics for Stripe), PopSurvey (create surveys people actually want to take) and Temper (improve customer satisfaction over time).
