You are not just selling homes; you're selling a lifestyle in a community – get out there and tell people why it's such an awesome place to live and what's exciting about the real estate there and they will start thinking that you're a pretty awesome choice for their real estate transaction.
Your blog can be looked at as an extension of your personality; it can be an ideal way to let your clients (or potential clients) get an idea about who you are as a person. Don't just blog about boring old stats, let people know what's going on in your area! The average person doesn't want to read a pile of graphs about housing statistics; they'd rather have you tell them in your own words.
