Easy Traffic... The low hanging fruit...
This really is money for Jam. If you have good content, people will tweet it, because people are addicted to Twitter, and just love to Tweet... give them half a reason to and make it easy for them, and there you have it... next thing you know, thier friends will be checking out your stuff, and tweeting it to thier friends and so on.
This is insanely simple, and you don't even need a Twitter account for it. Simply find a "Tweet This" picture that you want to use, and give it this link...
http://twitter . com/home?status=Check%20out%20this%20cool%20thing...%2 0http:// www . url . com
Obviously replace the message with whatever you want. You will notice that spaces were replaced by %20. Also, make sure your message is less than 140 charactors including spaces.
That's it, nice and easy... give it a go.
