Lack of self confidence. Don't want to participate in discussion which they think is absurd or pretending to be smart because they think all who write in Sajha are dumb. But silently check each and every thread and get entertained. They cannot counter attack the person whose reply are absurd. lacking behind in discussion.
All ladies out there if you want to improve your discussion skills you should join sajha discussion in any topic. rather than checking facebook pictures every minute of same person each and everyday.
