When I joined Twitter on March 30th, 2007, I had a handful of followers (all of whom were friends, who had been on Twitter longer than that, who followed me back).

I remember my doubting wife saying, “If that stupid site ever goes anywhere and you end up with a bunch of followers - I’ll blow you.”

I then inquired “how many is a bunch?”

She replied sarcastically, “4000.”

4000, people.

4000.
