All-Inclusive or True Enthusiast?

While writing the posts for my blog about Manchester United, I've been conflicted about how to effectively cater to my audience. This problem originates from not knowing exactly what my audience consists of. Is my audience other Manchester United fans? Is it other football fans? Is it anyone who might just happen to be reading my blog? I've been writing under the assumption that my readers know a reasonable amount about English football and the bigger name players on the bigger teams.

Although I've decided to write while assuming a relatively high degree of knowledge (for now), I'm still left feeling that it might not be correct. My current feeling is that if I were to explain everything and introduce every player so that everyone could understand, there would be a lot of superfluous information for my more serious fans and the blog would be watered down. But if I keep my blog as is, and don't explain everything, I'm making it nearly impossible for those who don't follow football to become interested.

I'll probably keep my blog as it is. When it really comes down to it, I suppose it's important to ask the question, "Are people who don't watch much Premiership football actually going to read my blog seriously?" The answer: probably not. In fact, this conflict probably wouldn't have even come up if I were creating this blog on my own, outside of class. But for the purpose of a writing class which requires peer review and more general participation, I may have chosen a topic a bit too narrow in scope.
