Advertise only what you are willing to answer. A tried and true sales/marketing 101 basic that needs to be a refresher
course in Web 2.0.
I look around these expanding social networks and see many faux pas committed among real estate professionals, real estate coaches, real estate speakers, real estate service providers, and marketing and sales folks.
Unresponsive behavior.
It is an especially strange sight to see from social networking and marketing trainers. I have seen an abundance of preaching when it comes to providing the consumer with information and being responsive who I have seen turn around and not practice what they preach.
To earn respect, you should own it and give it. Giving does involve being responsive to prospects.
When you design your business/marketing plan for 2009 and it incorporates social media/web 2.0 (which it needs to) make a commitment to yourself and your business to be responsive and proactive. Reach out, engage your audience, and reciprocate their conversation.
Blunders I've been noticing.

Blogs: A post is written by a blogger and the blogger never comes back to the blog to return the conversation and comments in kind.
MicroBlogs: A person signs up for Twitter and never responds to their replies, denoted by using @(yourtwittername). It's easy to respond and check up on the conversation. Hit the "@ replies" button they give you in Twitter and you can respond without having to be logged into twitter 24/7. It takes literally 10 minutes to respond to several @ replies because you can only write 140 words.
If you are @the_real_shaq (Shaquille O'Neal's twitter name)or on that celebrity status level, you are inundated with @replies. You are given a reprieve. For the rest of twitterland, I have had @robertscoble reply to my @replies, so there is no excuse. You may not get to everyone, but get to some. It IS supposed to be a conversation.
Social Networks: A person signs up for Facebook. Facebook makes it easy and quick to write comments and feedback. If you befriend someone and put a value prop. out there for your business, and they ask you a question to which you are unresponsive it's like an unreturned phone call.
At least three service providers have lost my business in the Web 2.0 space due to unresponsiveness, casual aloofness (the "I'm too cool" to be attentive attitude), or carelessness.
Beware of automation. It may appear to be easier, it can also become a business killer.
Find a way to respond faster, time isn't slowing down and neither is the internet. Common courtesy, respect and general interest leads to relationships. Lack thereof kills them before they start.
Syndicate your heart out, BUT REMEMBER, Advertise ONLY what you are WILLING to answer.
great post - and reminder to start my 2009 business plan - Happy New Year!
