In any form of expression driven by public participation and desire for an audience, trends will develop. Whether you're talking fashion, artwork, music, slang, marketing, social media, scientific inquiry, or any number of other dynamic human forces, popularity and the desire for approval will affect what direction expression takes. One of the biggest areas of social life where trends can and do take over is in storytelling.
Over the weekend I attended a local book festival that is said to be one of the biggest in the tri-state region. I find that label a bit disappointing, but only because I feel it could have been better organized. The hosting organization had set up two tents in a community park, one for YA and adult literature and the other for children's books, and there were several vendors in between these tents. For as large as the park happens to be, I feel a third tent could have been added rather than packing the authors inside the two tents like feathers on a goose.
There is a lot of advice floating around out there concerning growing your social media followers and how to promote yourself (something every writer wanting an audience needs to do), but the marketing gurus I watch don't seem to receive much interaction from their tens or hundreds of thousands of followers. Maybe their analytics show that their posts are getting a lot of views, but I can't help but notice that they aren't getting very many likes or retweets... So how effective is their advice if their followers don't seem to believe it's worth sharing?
