For Teachers (Librarians), blogging at work:
"So, here's a short list. This is open-text, remember, so we can all play along.
1. Decide carefully if you want to create a public space for your ideas with your name on it. Maybe going anonymous would be better. There are a couple of great anonymous teacher blogs out there, Hipteacher among them.
2. When you write, assume it will be read by the very people you may not want to read it. Think about the consequences.
3. As much as possible, blog on your own time with your own equipment.
4. Tell the truth. If you can't, don't write.
5. Ask people's permission before you write about them in your blog, especially if it revolves around some struggle that you might feel worth reflecting upon or sharing with your audience.
6. If you do use a blog for professional reflection or opinion, my personal wish is that you take the time to present those ideas well. I'm not perfect when it comes to misspellings or errors, but I try to read everything at least twice if not three times before publishing.
7. Start simple, and find your groove. If you just post about news and don't add much in the way of commentary at the start, it will give you time to develop your voice.
8. Again, if you decide to blog openly, don't try to hide that fact from peers or supervisors.
9. If you think people may have an issue with your blog, ask first, and make your decisions based on the feedback you get.
10. If you find yourself looking over your shoulder, don't blog.
