very cool! i joined back in December ‘06, but didn’t really think about how big it would get…
I was surprised to discover I had joined twitter in October 2007. I assumed it had been later than that.
I originally joined December 2006. I left because “i didn’t get it” I then rejoined in March 21st, 2007 (1 year anniversary of Twitter). And I was in the 700Ks for my user account so I joined before they hit 1 million.
I did 20K tweets in my first year
19,850 tweets in my 2nd year so I did nearly 40K in two years. not bad.
Well:
I joined twitter on 13 March 2007 – http://whendidyoujointwitter.com ?
There must of been an article around then about it, or news because wilw joined the next day.
