Are multiple blogs about writing a good idea?

When I decided to blog about writing, I created two blogs:

Head Over Writing to blog about all things writing. A place to share writing courses, things I’ve learned, quotes, book reviews, prompts, snippets. Random and quirky things related to reading and writing fiction. (Twitter: @HeadOverWriting)

Also, KJ Carine (A fiction writer’s journey) – more of an “author blog” to specifically blog about MY writing process and projects – currently writing short stories for magazines. (Twitter: @KJCarine)

My questions are:

Do multiple blogs dilute the impact that a single writing blog would have? Or is a single blog sometimes less appealing if it tries to cover everything? 

Do you have one writing blog, or more? 

Are you thinking about creating additional blogs, or consolidating multiple blogs?

Please share your thoughts or experiences in the comments section. I’m interested in hearing and learning from all of you about this!
