Google Memorial: the small museum of projects abandoned by Google
I really don't like things like this.  A lot of these projects ended up as other projects or built into other projects.Google checkout turned into Google Wallet.
Google latitude ended up as part of the Google+ Identity overhaul.There's also a lot of projects that are "labs" or "beta."  Clearly they didn't gain the traction Google wanted from them.Google's like any other startup on a project-by-project basis.  If the idea doesn't work they pivot and drop it.
