How do you select the topics to respond?

I respond to a discussion only if I think that I have something valuable to say. The topic of discussion should be interesting to me. I don't respond just for the sake of responding. I try to respond to the disussions started by my friends, if they are atleast a little interesting. Sometimes, I got to the 'new' tab on top of the menu bar and respond to some random discussions. I also go the topics of my interests and respond. Sometimes, I go back to the 'responded'tab and see if somebody has commented on my responses and respond back to them. I also comment to the responses people give for the discussions which I created.

I respond to topics that are under my interests. I also look at new discussions and those without responses. Whenever I see something interesting or if I feel I could say something about the discussion, I'd respond to the topic.

Hi, i answer just in topics where i have something to say, never just only in my friends topics. Here is not a trade, is just a open place where we can answer what topics we like more. I don t have a preferate subject, but if i see something intersting for me, i will answer for sure.
