Hi,
yes, PlayMaker has a massive scope of possibilities, but here we are talking a different kind of context. PlayMaker is not suitable to build the Back End of Facebook, it is suitable to build the Front End.
- Back End means the "brain" on a server or cloud that deals with data, logic, protocoles, and rules for running your social network,
- Front End means the client application on a mobile phone or website pages served via your browser, they act like an interface between the user and the Back End. o we have forms which lets you login, or make a comment, click on a "like" button, show how many followers you have, and their images, etc, but the Front End is merely making requests to the Back End, the Back End responds with data, and content, which the Front End shows to the user.
Does that make sense? and so in this perspective, PlayMaker is only part of your system, you can make the Front End with it, and it will be perfect for the job, no limitations at all on that regards, but for the Back End, this is another story, and you'll need to know either php/mysql, or asp, or any of the many server side systems available to build such back end.
Needless to say, that the backend development is likely going to be the hardest part of building a social network, you should definitly look into pre made turn key solutions, because starting from scratch isn't going to get you anywhere without prior experience and expertize in that field.
