How many social media sites should be used?
While there are hundreds, if not thousands, of social media sites out there, its impossible to use them all. Generally, its more effective to use a small number (I recommend 2 to 5) actively, and if you want to have accounts at other sites that you use ocassionally, thats fine. Because part of being a successful social media user involves building a profile and a reputation at the site, it is much more realistic to achieve this when youre using a small number of sites consistently.
