Let's see, the data is that all the users that have signed up before they changed their security, have signed up before they changed their security. Since they changed it very recently, but have been around for years, I think it's a safe bet that my statement is correct.
Fine, what I really meant to say was "accounts", not "users". In my framework, I only consider "users" those who signed up, so I usually refer to accounts as "users", but technically this may be incorrect.
There are 20 million accounts, 125 thousand active accounts [1]. The number of people who refer to Wikipedia is probably over a billion, since it's often the first hit in Google (speculation). Roughly 25% of edits are anonymous (no account), and anonymous edits are significantly longer than non-anonymous ones [2].
