I too like IRC but don't you think people would then rather ask in IRC than in forum.Isn't purpose of forum getting defeated?

Negative.
Because in this case, as stated by Anima Templi, most of the community here wouldn't bother using it to begin with.
Currently there're only two people in the channel. Me (and here at the same time) and JesseH himself.
Which of course is supporting evidence that the majority here will not use it accordingly.
