Google's social buying spree

• Google's new social networking strategy

In the week following Google's Like.com purchase, it bought Angstro, a social networking search application.

Angstro's applications can help users create a social network address book, find Facebook photos, and improve their caller ID by using their social networking contacts, among other things.

Google recently partnered with Twitter to let users search all tweets in real-time. Angstro's apps could be useful to Google, particularly in its Android mobile platform, to help users find and access data from across all of their online social identities.
