You just might be a social networking addict if..

1. You ask hosts at a dinner party what their foursquare privacy policy is
2. You go ahead and check in anyway
3. You check in on any of the following google latitude, fring, facebook, booyah, citysense, brightkite, gypsii, mobiluck, loopt, plazes, whrrl and IPling
4. You actually know what any of the sites in bullet 3 are and/or actually use them *Bonus points* if you know and track which of these have received recent VC funding
5. You get upset when a work colleague unfollows/unfriends/blocks you. You can no longer DM them. They happen to sit two cubes down from you
6. You engage in riveting debates on the pros and cons of using twitter vs. yammer for work. *Corollary* You frequently engage in social networking proselytizing at work
7. You ask at a work meeting if there are hashtags for any of the action items
8. You are deeply vexed on whether to make a particular link public or private on your delicious site
9. You are a mayor on foursquare and make it a point to tweet about it
10. When doing something remotely fun - You must check in, see who else is around, view their profile, friend them, tweet/yam/fb about it - other than enjoying the bloody thing you're doing

Even if none of the above are true, you are a social networking addict anyway - that's the only way you would have gotten notified about this post :)
