In the case of so many options for social media outlets, where should your young person spend his time to have the greatest impact? How do you link his talent interest to the right community?
My answer: the key to using social media effectively is to understand that social media is NOT a generic medium for broadcasting to the world, but rather each type of social media is best suited for particular types of communications and communities.
This means that if your son or daughter’s talent is primarily visual in nature, then you need a social media that is best suited for visual communication. Twitter in that case is very ill-suited to showing and sharing your knitting projects because the visual part is not its strength. Facebook is also ill-suited for knitting because it is very poor in helping you to connect with other expert knitters. But Flickr or Instagram for knitting is very good because it is very visual AND you connect to other people on the basis of shared interests, not on the basis of a shared past like Facebook.
On the other hand, if your young person is into a talent that is very time-sensitive and event oriented, such as running marathons or participating in kayak races, then Twitter is the ideal medium for communicating quickly within those expert communities with bare facts of statistics that can be read with mobile phones while on the go.
In almost all cases (I can’t think of any exception), a blog is an important component to creating a living portfolio of your child’s talent progress. Strictly speaking, a blog is not really a “social media” medium, but it feeds into that idea of communicating with your talent community. The main point of using social media and a blog is that your talent has something of value to communicate to particular communities.
