Google announced on its official blog yesterday that it has acquired Zagat.

Google continues its acquisition drive with Angstro, which is a social networking startup. Angstro has a unique feature of pulling in data from various social networks and websites like Facebook, Twitter and LinkedIn.

Plink developers claim it has been downloaded over 50,000 times in the last four weeks. The two founders of Plink, PhD students Mark Cummins and James Philbin, will now join the Google Goggles team and help enhance their own product under Google.
