One thing about me that my clients quickly figure out is that I have a sense of humor and most of them love it. YES, I have run into those clients that aren't sure what to think of my humor, but I understand that we may not be a match and I introduce them to someone who may be more their pace.
But, when I met a potential client for the first time who found me online, I usually get the reaction "You are funny online, but dang, you are even funnier in person." That, to me, is great. But I do my best to be myself online... serious when I need to be, but with a little sense of humor thrown in. (This must be the reason for the weight gain, my sense of humor is just growing.)
What if my potential clients came to me because of my blog and I wasn't anything like what I portrayed in my posts? Would they still work with me, if I wasn't there to help them and try to make the situation the least stressful as possible by adding a little humor to the situation?
Personally, if I had read something about someone, felt we had a connection, and then went to meet them and they weren't anything like what I was reading online, I would be turned off and walk away. So, do what your mother taught you to do and be yourself online and in real life.
A lot of people believe that real estate is going the way of the internet, but I actually disagree. I think real estate is still about people, our online presence is just another advertising and marketing tool that helps us build our business, it doesn't run our business.
So don't forget that real estate is still a people business and your blog is only an extension of you.
