they do say not to make your blog your best friend, and in a few ways i agree. when i comes to business, as in you have your blog connected with your store, then yes, it should be more professional then full of rants...and that's why i have two. i love my inspiration blog, because that is an enormous part of my life.
BUT, i love this one, too. i like knowing that if people want to see a real side, then it's here, too. i've always felt that being yourself is important.
