- All you wear are geek shirts / social networking shirts, and only geeks know what they mean.
- You call your family members and friends by their Twitter names.
- When you see people you haven’t talked to in a long time they ask you: “Are you going to tweet about me?”
- Your last two social gatherings were Tweetups.
- You have Instant Message, Twitter & Facebook chats with your spouse and you’re in the same house at the same time.
