I am usually the first in responding to Discussions with no response

That is what better known as "Individual Social Responsibility or ISR".You are not the only one doing that i guess..

Do they reciprocate?

I enjoy browsing through that section also!

I don't usually get a chance to be the first person to comment on a discussion here, but when I am, I rather enjoy it! Gives me the chance to have my say and know that I've given one more person some feedback!

I do occasionally check out no discussions but most don't stimulate. Not everything is for everyone.

I go to there first and respond to responseless but interesting posts.

I just wrote a discussion with no response yet. Im not sure though if you have glance over it already. Lol! anyway, i usually also respond to discussions with no responses. The only discussion I tend to not respond to are those I cannot understand or those written in text speak because I know they would easily be deleted by mylot.

One good way to make friends, especially new users

That's nice of you. I hope people are paying the same attention to you.

I often check out posts with no response too but I pick and choose which ones I respond to. Lately it seems there is only a few showing up on the page.
