Happy medium: Writing about topics you like VS. writing about topic your audience likes

I was talking to Sean Murphy yesterday (who I met at the Online Community Unconference) and mentioned to him how difficult it was to write about communities alone, given that I have a wide variety of interests.

He made some very good points about the importance of focus. The fact is that over 300 subscribers to this blog are “community related” and about 200+ are friends with various interests.

I think I hit upon an idea after talking to him about possibly being a guest blogger on other blogs that focus on topics that interest me but are not related to community. I am going to reach out to a few friends and try that concept out. So topics of Investing, Enterprise Software, Marketing in general would be available from other blogs with a possible “plug” on this blog alone is a concept I am mulling over.

Similarly I would offer to have others in areas of their interest talk about community from their perspective on this blog.

What do you think? Have you tried that? Does it work.
