I set up the initial CSS and wrote out the blocks of HTML that the AB engineers turned into CMS modules that became AllBusiness.com. I maintained the CSS and was the Senior Producer through August 2010. The startup was acquired by NBCi in 2012. When the domain was reacquired by the CEO years later, they brought me back in to help port it over to WordPress. It looks to have been updated since then.
