But will fickle young users stay loyal if something new comes along, and are they the most lucrative market to tap for advertising? Share Radio's Matt Cox spoke to Leslie Pfrang, Partner at Class V Group, which works to prepare companies when going public and handling the IPO process, to discuss what Snapchat's move means for the IPO market.
