Google (NASDAQ: GOOG) is no longer the little tech-startup that could. It's a powerhouse; and its 23 acquisitions thus far in 2010 are an indication of that.

Three of these purchases fit into the content management arena: Plink, Angstro and DocVerse. 

In March, Google picked up DocVerse, a tool that let multiple users share and edit Microsoft Office documents online. The purchase gave Google a way to bring Office users under the Google Docs umbrella.

One month after the DocVerse purchase, Google bought visual art search engine Plink. The acquisition was aimed at improving Google Goggles, which initially had mixed reviews.

The most recent acquisition of 2010 came in September and was not targeted at enhancing a current Google feature; rather, the purchase of Angstro would likely add to Google's social networking strategy. The social start-up reportedly aims to find a highly relevant set of results from a defined set of sites.

It's no secret that Google has been searching for ways to make social networks interoperable, and the purchase of Angstro was likely a smart addition to that plan.
