Why you should be selective for online dating? Because maybe she/he isn't like what they say. Don't just make a choise based on picture/webcam chat. Why? There's many site provide good looking picture and recorded webcam chat video. So maybe some people use that while chat with you.

There's no exact way you can take a deep look about someone if you just sitting in front of your computer. But there's also some way you can get little picture about person you talk with.

This is some tips.

• Make a topic that can lead him/her to talk more about himself/herself. Don't only ask do you single? what's your favourite? etc. Make advanced self description question. Lead him to talk more deep and draw him/her in your mind. Is she/he match with you or not.
  
• Choose people who live in same city/town with you. By doing this, you can shorten you online chat time. If you're living in same city/town ask for dinner or walking or something else. Don't just waste your time in front of your computer. Make a move.
