As the industry was shook by one earthquake after another (first Microsoft’s deal with Facebook, then Google’s OpenSocial move), many asked, “Where’s Yahoo!?” Well, it turns out that “where?” is an important question to the folks at Yahoo!’s Brickhouse. I learned about the impending news via Michael Arrington’s Twitter post this evening, which I saw in my Plaxo Pulse. Minutes later, TechCrunch broke the news about what looks like a very exciting and open play around geo-location APIs and services. This is, indeed, a critically important piece of the open social web. Will be interesting to see how/if it hooks up with the Google OpenSocial stuff.
