Every time Google is shutting down a product there are the same kind of reactions like “I will not trust google running anything more than a year”, “killedbygoogle.com”. I’m wondering, have you ever heard about this product? I for one have no clue what this is. How many more products does google have that you never heard about and that are not shut down?
Yes, but what about the people who did? Here's the thing, Google is a big company. When a big company offers a service or product you expect a long shelf life so you can justify the time/money investment to use it. If you stumble across an open source or just some other random project by a single dev, you have an instinctive expectation that the project could die at any time. Thus, you invest your effort accordingly…
A decade ago I was an intern at Google. One of my mentors said something that has stuck with me: "Google found a hose that money pours out of and it's name is online advertising. All we do now is desperately try to find another hose."
Google's strategy for a long time was: Hire every clever person you can; give them some creative freedom; see if any of them come up with a trillion dollar idea.
Only now they've 'grown up'. 20% time is dead. There is no second hose. They've mostly given up on the idea of a clever person finding a new money-hose. They just focus on the one they have now.
