I'm afraid that I'm not sure which comments you are referring to. Do you mean the comments next to your photo on this page or the 'No stats yet!' verbiage on your profile? If you mean the latter, that text will be removed once you start to answer Trulia Voices questions and replaced with the total number of answers you've given, as well as the number of Best Answers, First Answers, and Useful Answers you've provided.
I hope this answers your question.
