Which all, and how would you use social media to project higher value?

So many people value social media so much, so I firmly believe that there is some way that this can be used to cruise through a lot of situations by already having a powerful presence on social media. Or a lack of presence.

What do you guys think?

Having Facebook, Twitter, Instagram and Snapchat seems like oversaturating yourself.

I firmly believe it should be either Facebook or Instagram, and twitter or snapchat. But what do I know, I don't use these sites.
