Ever scratched your head in a conversation, thinking back to your first taste of Twitter? I always knew when I joined... approximately. After hearing about the service so much during virtually every session at SES New York 2008, I jumped on the bandwagon. I was hesitant at first, went through a stage of protecting my Twitter stream, and opened it up again only recently. Approaching my first Twitterversary, I wanted to let you all in on the secret so you can buy yourself a cupcake and calculate the time you've wasted enjoyed using Twitter.
Go to http://twitter.com/users/show/yourusernamehere.xml It's that simple. The first date you'll see is the date you joined - mine was the third day of SES New York, at approximately 3pm (I'm on London time normally, so that's what it shows). Simples!
A big thanks to Kate Morris for the lightbulb moment.
