As a professional writer, your image and reputation are important. There are numerous blog posts, articles and discussions on professional behavior, but a visit to the BookEnds blog reminds us to be careful what we say out there. Content on the internet is permanent. Even if you attempt to delete something, there are services that have already harvested your page for future display, visitors can save pages or create screenshots. So think about how you want to appear to the world the next time you post to your blog. Or Twitter. Or Facebook.
