I love reading everyone's 'about me' pages and learning about the faces/stories behind the blogs!
For mine, I broke it down into sections. The first section summarizes what the blog is and what motivated me to start it. The others talk about the inspiration behind the blog (the "real" Bubby & Bean), the line of art that goes along with the blog, and a short bio on me/my career. My reasons for starting Bubby & Bean were sort of intense and I wanted to include the full story, but too much wordiness can leave readers bored. So I broke it down into "parts." :)
