after i responsed a discussion,i would like to ...

I found many users like to response his discussion immediately after his posting, but ignore the rest part given afterwards. Perhaps he has no time, or there are too many reaponses for him to answer. I even experience this process. It's a mixture of excitement and fatigue---eyesight fatigue, but still feel happy.

Whstthis ?

I think this would require a lot of effort but for good discussions I would do it
