Let me share how I do it. I have my main site,
Redhead Business Solutions, when you go there it's strictly business, I talking about things that would be useful for my readers related to Wordpress, 1SC, and Aweber as well as Online Marketing since that is my focus.
I also have
ReneeShupe.com at the moment this is more personal, I only write when it strikes me and it can be about anything.
Now, depending on how you want to focus your blog you can keep it all business, or you can have more personal stuff. My personal thoughts on it is go ahead and share personal aspects and stories on the blog, but keep them tied into your business in some aspect. Don't go too personal, if you want to do that start a personal blog.
Now if you are using Wordpress or pretty well any other blogging platform you can always delete a post down the road, but it can be cached (stored) somewhere and may come back at some point down the road, just something to think about. I have a new Blogging Tips series starting today on my blog so if you're new it might help. I think that this would be a great topic to add to the series! So thank you for that, I'm going to write a blog post about it at some point in the next few weeks.
I'd love to hear what others think....
