I sure do. by answering questions people have been drawn to my web site and i have received more exposure for myself and my listings. I have 2 recent buyers who were surfing on Trulia and clicked on my link. One purchased one of my listings and the second we are looking for homes currently. In addition by listing my homes here as well, i have been able to increase my exposure to potential buyers. the stats are very helpful as i can forward them to my sellers and use in my marketing. the whole key in answering questions is to provide a personal answer and try not to advertise yourself or your properties in the question and answer area. i hope this helps.
I have not gotten any direct busines yet but have been emailing a number of people in regards to questions that they contacted me about and that is the first step.
