Is Twitter's growth slowing down? Only 15% of respondents to a February Pew survey of U.S. adults claimed they use Twitter - that's up just slightly from 13% in May 2011, and well below the 50%+ penetration Facebook had reached at a similar point in its history. A slowdown, together with the recent slump in social networking valuations, could make Twitter more amenable to an offer from Google (GOOG) or another party. However, its international growth appears to be healthier.
