Ok so I've run a blog, as an extension of my business's website, for over a year now. It has been all about topic A.
Now my business is developing products for topic B, and as such, I want to start blogging about Topic B, which is really not related to Topic A. I want to continue to blog about them both but I don't want to confuse or annoy readers by mixing both topics.
What is the best way to handle this fragmentation? Should I:
a) Keep everything on one blog using Wordpress's categories (problem: the main blog page will be intermixed with Topic A and B)
b) Install new blog software in a different directory on my website, basically keeping both blogs separate
C) Some other solution?
