To niche or not to niche your blog

When I started blogging, I looked around to see what the experts recommended and, time after time, they said to have a focus for my blog. Write about one topic. One. Have a niche for your blog and you’ll get an audience that knows what to expect and that will respect your blog.

So, I did. My blog focuses on writing, books and reading. That’s it…ahem. I do comment on my daily life from time to time and tell readers about my dogs and other funny bits, but the majority of my posts are on topic. I try to follow their advice but, now, after a while, I started wondering…is that good advice?

Here‘s a post by Jessica Lawlor who argues against the ‘experts’ and leaves her blog unfocused.

What do you think? Is that a necessity for a blog? Do you as a reader turn away if you find a post that’s not on topic? Is that too rigid? Do you follow that idea with your own blog or are you more relaxed about it?
