Los Angeles-based Realtor.com, the online real estate listings site run by Move.com, said earlier this week that it is looking to spur blogging on its web site by Realtors. The firm said that it will help Realtors to create blogs, and post articles, comments, and messages on both the Realtor.com web site as well as within personal web sites. The company said that its new blogging program is designed for non-technical users who don't know HTML.
