Google (NASDAQ:GOOG) continues its acquisition spree, snapping up startups Katango and Apture for undisclosed sums. Katango provides tools for automatically grouping a user's social networking contacts (potentially useful for Google+), while Apture develops browser plug-ins that allow search results to be pulled up without opening a new tab (already useful for Chrome).
