The outbreak of million's of Facebook users has beaten e-mail!!
Although some persons use email different than other ( maybe work , news letters)
But the twitter and Facebook users have found faster more reliable way of chatting in the world
Like using Facebook chat or twitter updates.
Just look at the difference:
social media ~
1. you might post some photos on Facebook rather than e-mailing it
2.you might chat faster on Facebook than e-mail
3.you can quickly watch what your friends or family was doing ( I don't think you will e-mail them to ask that )
E-mail ~
1.need it for most of the websites (to register)
2.Might be for work
3.More personal
E-mail might stay as the more personal and classy way, but Social media will stay on top!
If you want to social Media combined with Email, here is a few tips:
Use Facebook messages to send messages to your followers or friends.
Use direct message or reply's on twitter
Give your email to the world! If I can't find your email, I am not going to email you.
