Currently I have one Blogger user profile with a single blog. The user profile has been implemented to be congruent with the topic covered by the blog. For example, the image is of a smart looking guy in a suit and the personal details of a banker. The topic covered by the blog is to do with finance. If I want to branch out into other unrelated niches, will my blogger user profile become an issue? Is it best to create another? Or will this not matter? I'd like your input
