TECH CRUNCH - Feb 28 - Sonar,
a social discovery service that was among the top apps at last year’s
SXSW in Austin, is announcing new investment from Bing Fund. This angel
fund and incubator program from Microsoft was publicly revealed this
summer, allowing Microsoft to partner with entrepreneurs, which can then
receive subsidies to use Bing APIs in their apps, as well as access the
technologies developed by Microsoft Research. Sonar’s app uses
check-ins on Facebook and Foursquare, plus geo-tagged tweets, to show
you lists of nearby people, ranking them first by friends you know, then
showing you other relevant people nearby.
