1. Bloglines, Google Reader or some other RSS reader is constantly open on your computer's desktop.
2. You tell customers that you missed a project deadline because "some things" came up but in reality, you were blogging.
3. You periodically dream that you are blogging.
4. You get inspiration for new blog posts at the strangest times - in the Jacuzzi, sitting on the toilet, during marital activities (cough, cough)... you get the picture.
5. Before blogs, you used to tuck the kids into bed at night. Now you check for unapproved blog comments before heading to bed yourself.
6. In order for your family to keep up with what's going on in your life, they have to read your blog. Furthermore, if they want to communicate with you, they have to comment on your blog.
7. You have actually considered setting up a blog for your pet of which you would post the entries pretending you are your pet (weirdo).
8. You can't remember dates for your wedding anniversary, kids birthdays, etc., but you know what your Technorati rank is.
9. You blog about anything and everything including bad meals, your pets, getting your car stuck in snow, conversations you have in the bathroom, etc.
10. Keeping a blog is no longer enough but you now have to record your every move on Twitter.
We hope that this blog has not led to any addictions :)
