I signed up at Twitter 9 years ago and use it every day, but have less than 50 tweets. Either you want to engage in discussion (to a varying degree) or you simply don't. But the latter doesn't necessarily mean you don't observe the discussion.
Of course an active Twitter account can be one that never tweeted in 10 years. Such an account may as well see advertisements etc... So I think any outside studies are fundamentally flawed since they don't have access to internal data like last login time.
