Not realizing that your explicit blog could have a negative impact on the rest of your (personal and professional) life. By extension, thinking your blog is immune from society's judgements.
Named for popular Washington DC blogger Jessa Jeffries who was fired for her blog, Jessaisms, a Jessa Complex describes the habit of young, hip bloggers to post their entire lives on the web with no regard for professional consequences. This often results in a blogger being fired for the contents of their blog, otherwise known as being dooced.
I think she is developing a Jessa Complex. Her blog is getting really personal. She'd better watch out or she might get "dooced".
