File this one under the "ouch" category. Yahoo is shutting down its social-networking experiment, Yahoo Mash, after .
An e-mail to Mash members from Yahoo community manager Matt Warburton read, "Thank you for trying out our Mash Beta service. We hope you had fun with it. Please note that we will shut down Mash on September 29, 2008. As a result, your current profile on Mash will no longer be available."
Mash didn't really offer anything new, other than the fact that instead of inviting friends you created profiles for them and then invited them to customize and change them. You could also add "modules," a sort of rudimentary version of social-network apps. It was designed as a quirky, cute step up from Yahoo 360, the social network that Yahoo had based off its millions of pre-existing user accounts; if Yahoo 360 was analogous to AOL profiles, Mash was more like Facebook.
But Mash never caught on, and its parent company has now deemed it worth closing.
This is not the first time that Yahoo has launched an experimental social network only to yank it. Last year, Yahoo shut down a Dodgeball- or Brightkite-like mobile social site called "Mixd" that had only been in operation for a few months.
