Lol - the code example seems to imply that Zuckerburg's user id is 4.

That's because it is 4!

As a ruby programmer, my gut reaction was that this had something to do with bugs caused by the object id of `nil` being 4. But of course that's not the case :)

You need to upgrade your Ruby version. The object id of `nil` is 8 these days :)

[sanderjd]

Ha, well they also got rid of `id` on nil altogether, so it stopped being a common bug. (I didn't know that its object id is actually 8 now though, so thanks for the useless-knowledge-nugget.)

Who is 1,2,3 ?

My guess (and there may even be apocrypha about it), is that these were old registration test accounts that didn't survive the first Zuckerbergian purge.

[leebyron]

Correct. SQL auto increment keys plus test accounts resulted in Zuck being 4.

It is :)
