For a couple of months now, a post has been swirling around in my brain that I was tentatively titling "The Dawn of the Mashup Culture" in which I wanted to talk about "mashups" and why they are so incredibly important. Unfortunately I just haven't had the time to put all those thoughts into the written word.
Well, in the meantime, Jim Courtney went off and wrote something very close to what I was intending to do: "The Dawn of the Mashup World - Part 1: Challenges, Why and Expectations" followed by "Part 1a: What is a Mashup?"
Read them. (And the follow-on posts that Jim indicates he's writing.)
Mashups are fundamentally changing the way we can use and control services. It's the remix culture.
You need to understand it... because if you don't, your products and services will be left behind.
Open APIs win. Mashups win.
