I think too many bands and businesses are treating social media like it is their chance to run commercials all day every day. Every post is a sales pitch, a request for the reader / viewer to buy something.
This is despite the fact that everyone I know who records a show on TV fast forwards through ALL of the commercials when they watch it later. These are not people hungry for advertisements.
And I realize that bands and businesses want to sell things. But if you want to hold someone's attention, if you want to give them a reason to keep tuning in, balance things out with content that is interesting and does not have a "buy now" button attached.
