That is a seriously depressing tumblr.

Surprising how many companies Yahoo has been gobbling up... and shutting down. What exactly _are_ they doing with all the new hires?

Even when they don't shut them down, they can often turn gold into shit. See Delicious, Flickr (before Melissa Mayer) and so on...

Google actually does a better when they decide to keep the product (Android, Blogger, Google Docs...), but it's impossible to know whether they're buying the product or the team until they either integrate the product or shut it down.
