Hook is the link-everything app for your Mac. It creates links to files, email, and other digital bits, letting you easily “hook” things together. It’s increasingly becoming part of my contextual computing workflow, and this week it turns three. You can get 30% off with the code: “HookTurns3”.

My initial concern about Hook being a flash-in-the-pan is now obviously unfounded. They have a solid business model and the principal developer is clearly committed to making Hook work for everyone. (Note: I agreed to accept an unpaid and uncompensated position on Hook’s board of advisors.)
