have you always thank people who respond your discussion

Yes i always try to reply to the people who respond to my discussions. But i only reply to those who have something of substance to say, not just one line answers like i don't know or i agree. I reply to all my quality friends, when they can take time out to reply to my discussions why can't i, maybe sometimes i'm late to reply but i do reply.

I not only thank tham, I also go deep into the response if their response required further more information.

Yes I always try to. It might not be the same day, but eventually I will post a reponse to their comment. It's good to keep your discussion going.

most of the times that i thank people for their comments is when they are really good and they really me.

yep

yup.. I have always did.. I just show appreciation to people who is willing to took the time to respond to me.. At the same time, I interact with about out opinions towards the discussion.. It's really fun and rewarding at the same time..
