According to Fusible, Microsoft accidentally published a webpage to the web that seemed to show off a project being referred to as "Tulalip." The teaser page was published onto the domain http://www.socl.com/ and the service is described as a "social search." However, the page has since been taken down by Microsoft, with the software giant only leaving a short note:

Thanks for stopping by.  

Socl.com is an internal design project from a team in Microsoft Research which was mistakenly published to the web. 

We didn’t mean to, honest.

“With Tulalip you can Find what you need and Share what you know easier than ever”, reads the message on the page. Also, you can see a Twitter and Facebook login button on the homepage. There are also tiles of people's faces on the homepage. 

It seems as though whatever this is, it's not ready for launch yet. But, it probably won't be long until we do see it.
