Keeping separate blogs is more difficult than you think. I mix personal and author stuff on my blog, hence the title of "other such nonsense".In my opinion, your blog is your journal of the journey to get published. Real life stuff is part of that journey, isn't it? Just makes you more human to see the personal parts if you are willing to share.
I hope the readers like how crazy I can be :) I think I'm going to do Mom Mondays and Teen Thursdays or something like that :)
