One’s Email ID and usage behavior could reveal some info about his online history:
* Email IDs like sumathy1999@yahoo.com or john2009@hotmail.com with recent years indicates the year the Email ID was created.
* An Email ID with a very common name like ram@gmail.com or james@gmail.com indicates he was one of the earlier and long time users of the service. No way such a common name is freely available.
* Email IDs like mary1952@yahoo.com or mohammed1969@hotmail.com with very old years indicates the year the person was born.
* An Email ID like biovishnu@xyz.com or mechsundar@123.com indicates the profession / interest of the person involved.
* An Email ID like writerkumar@gmail.com indicates that the writer is definitely Tamil and no global guy will recognize unless he himself declares as a writer 
* An Email ID like priya4raj@gmail.com or aruna4rishi@yahoo.com indicates that the girl is in love with that guy. Most probably the boyfriend will be checking her emails. Beware.
* Any email ID with hotmail.com indicates that the owner is an early user of internet who doesn’t know to move to better email services or he should be real dumb.
* A person with more than 3 email IDs (most likely from small sites) and checks it regularly is a newbie internet user.
* A person who keeps forwarding emails probably doesn’t use internet for anything else worth spending time.
* One who calls you to verify that you received an email is probably a grand father / grand mother who is excited to learn this internet stuff.
* One who uses Twitter instead of Email is a fairly advanced internet user.
Can you think of anything else?

* One who has the same handle in multiple i.ds (gmail/yahoo/office) might be a user who is ignoring mails to his old i.ds which might be premkumar2005@yahoo.com
* If someone is responding to a “You have inherited a piece of 100 square miles in Florida” or “Congratulations! You are a lucky winner of 1M $ in Grand Lotto, via your mail i.d” is signing in for the first time
* Someone who sports a thisismyemailid@rediff.com is believed to be have high IQ, wit and common sense.
Good one Venkiraja

For example, his business card reads:
E-mail: ravidreams@gmail.com
)
ravidreams@yahoo.com
ravidreams@wordpress.com (Say, you are working at WP
He is a seasoned user, and he doesn’t check mails which his old friends will possibly send to ravi.mit98@sify.com or ravieceking@hotmail.com. Got it?
*Also, @ymail and @yahoo.co.in users are probably recent users, than @yahoo.com users. Same applies for @live.in peeps vs. @hotmail.com peeps.
Understood the handle now. True.
The .in thing is good one too.
I strongly object to these 2 points. Everyday I use my HOTMAIL, Yahoo, Gmail & business Emails..
//Any email ID with hotmail.com indicates that the owner is an early user of internet who doesn’t know to move to better email services or he should be real dumb.
//A person with more than 3 email IDs (most likely from small sites) and checks it regularly is a newbie internet user.
Ganesh,
May I know the reason advanced users may use hotmail still?
Please note that I said more than 3 Ids from SMALL SITES like coimbatore.com etc.,
