Are you curious to know when someone first joined Twitter or even how long you’ve been on it yourself,  here are a few sites to check out !

When Did You Join Twitter? :  This is the easiest Twitter application you’ll ever find and the name explains it all. All you need to do is to type the twitter username into the designated box and click “Find out”. The user’s picture and Twitter statistics will be displayed within seconds. Created by Neville Ridley-Smith @nev, the application’s Twitter-like interface makes you feel the site is actually affiliated to twitter. Wonder when Twitter will ask the site to remove its trademark.

TwBirthday: I liked the way the site issues a Tw Birth Certificate in your name.  Enter your Twitter handle and TwBirthday will give you the Twitter birthdate . In addition, Twbirthday suggests who might’ve “godfathered”, their age index, and a break down of just how long a Twitter account has been active in hours, days , months and years. What the site means by “godfather” is unclear,  but probably the first person you have followed on twitter ?

Tweet Grader : This is another interesting tool and it also gives  the top users that joined Twitter on the same day.  I share my Twbirthday with @Pritishnandy and many others.
