Magazines are a tremendous resource, not just because of the articles and resources they provide, but for their perspective and predicitons on fads and fashions. Magazines speak for the people and about the people. A book is published and it either makes it or breaks it, but it is a one time effort per book. A magazine must sing to the choir repeatedly month after month, attracting readers and deperately hanging on to them over and over and over again. Few magazines make it to "success", defined as lasting more than five years. If they last longer, then they are worth investing in and reading.
Examine magazines for their inspiration, but also go through them and look for trends. We have a few to recommend to you for serious consideration.
