The discussions are very engaged with diverse topics being discussed by different members in various groups that I joined throughout my membership tenure at TFDCampUS (formerly known as TFI). Most people had never met before so it was great networking opportunity for me too! It is free but only open once every 90 days which can be quite frustrating if you want more frequent access or have limited time available each day/weekend compared other paid services out there like HootSuite etc.. Would highly recommend this service especially during these challenging economic times where online marketing has become vital part from traditional media advertising budgeting process.
