i was getting again 0 responses for my discussions..

You can add more friends so more mylotters can see your activities and give you responses. I was having this problem as well when I first joined and the discussions that I started didn't get much of a discussions but by the time went by, when I got more 'popular', I receive more responses. And of course, the topics should be decussive and interesting.

Same thing has happened to me when i was starting. The responses my topics has gained were very few but the numbers did improve as i added a number of friends (i still don't have that much though). Just be patient, hopefully the discussions you'll be starting will pick up. I'm just like you, still strugling to maintain a consistent and decent number of response for my every discussion started; but i won't give up just yet. :) i hope you won't too!
