Dissing Other Real Estate Businesses: The old adage “if you have nothing nice to say don’t say it” works for blogs as well. According to real estate personality and associate broker and Realtor®, Herman Chan, “There is nothing wrong with a strong point of view (after all that is the basis of a good blog), but keep it professional and light. If you trash a competing listing across the street, trust me, your own listing is going to get trashed. While you want your blog to inform and entertain, leave trash talking at the door because it has a way of coming back full circle.
