Bumburum number

Mathematicians have an interesting thing - the Erds number . In essence, this is the distance from any mathematician to Paul Erdös through collaborative work. At Erdos himself, this number is zero. For his co-authors, the Erds number is one, for the co-authors ñ two, and so on.

Recently, I was visited by the thought - what if you do something like this for Habr? Only not by co-authorship (how to count it at all, by comments?) But by friends. Such a theory of six handshakes in practice. The well-known user boomburum was chosen as the reference point. The distance from it to other users I, without further ado, called the number of Bumburum.

A brief retelling of the results: out of almost 60,000 users of Habr and Bumburum, a little more than 25,000 are connected, most of them have Bumburum number 3 or 4. The maximum recorded number of Bumburum is 10 (festgo habrat-girl ). A small note: for the purpose of the study, people invited to the site by a person are considered to be friends, even if they are clearly not listed as friends.
