I have the full version of mathematica. When I input "SocialMediaData["Twitter", "Followers"]" it prompts me to log in to twitter, i copy/paste the log in code and my output is :
SocialMediaData::notprop: Followers is not a known property for SocialMediaData. Use SocialMediaData["Properties"] for a list of properties. >>
It is the same for all SocialMediaData functions.
