Mobile apps are essential at events. Rob Cartagine, the cofounder and lead software developer of AppBurst, knows what apps need: They should have the functionality users want. In his post on Meetings and Conventions, Cartagine has a couple of tips for you as you develop your event’s mobile app. Let’s say you have an expo hall full of exhibitors. In that case, make your app a good resource for your attendees by including something cool like an interactive exhibitor map. “Mobile technology offers untapped potential to engage attendees and generate revenue for your organization. Work with a developer to create something more than a static reference tool,” Cartagine writes. (ht @lfelux)

Getting press attention. According to Joy Lin, a contributor on the  Social Tables blog, destination marketing organzations (DMOs) can build relatioships with local media  to bring press coverage to events in their region. Here’s the advice she gives them: “DMOs have the unique position of lending instant credibility to the groups that you work with, and you have considerable clout to engage media coverage these groups,” Lin writes. Inspired by Steve Schell, vice president of sales at the San Diego Sports Commission, Lin learned “three important factors to take into account in order to successfully mobilize your local media around any meeting in your destination.” These include finding an angle, making a financial statement, and helping reporters gain access to the meeting. Could be something to discuss in your next conversation with a DMO. (ht @JoyLinDMAI)
