Chicago continues to prove itself as a city to be reckoned with on the technology front. Companies like Groupon, GrubHub and Motorola  raised the city’s tech-moxie profile but the next generation of tech start-ups was the focus at TechWeek. The new four-day conference wrapped up Monday at the Merchandise Mart but partner events associated with TechWeek run through Friday. For an overview of the event, including some stand-out moments from its maiden voyage, Eight Forty-Eight was joined by Wailin Wong, business reporter for the Chicago Tribune.
