When I finally broke down and signed up with Twitter over a year and a half ago, my first half dozen handle choices - all based on my fairly unusual given name were taken by what appeared to be placeholders. (No profile, few is any tweets/followers/following and nothing recent). I'm surprised that 34% are active. I'd have guessed at something more like 5-10%.
