I don´t work with mobile marketing to much but I guess most of us active in the IM-area couldn´t have missed that mobile group messaging took a huge jump in Q1 2011. I personally think that this will be a big hit during the next year. I guess Google agree since they bought the Disco app (disco.com) not to long ago. Facebook is also jumping on the train with Beluga so I guess they see the potential as well. So, how are you mobile marketers gonna monetize on this shit then effective as possible?
