No, not really! If I get way too many responses then it's a whole lot of extra work for me to read all the answers each time & vote up (if applicable - some people put random or garbled stuff in their answer).
I was very surprised when one of my questions got over 100 answers, and 2 people made a hub each about the topic! It was a nice surprise in the sense that people were interested, but I wasn't intending to try to get as many answers as possible with the question... I just wanted some answers on the issue... and got more than I had anticipated!
