Peter Madden had a clever piece on AdAge on Friday, a primer on the seven personalities of Facebook users. Read his full piece for all his witty comments. Quickly, his seven Facebook user categories:

1. Super Moms.
2. The Thing. (Updates on what thing they’re into)
3. BraggaBROcious. (Male or female, they brag about their lives)
4 and 5. Emotionally Yours and Constant Contact (Obvious)
6. The Drinker/Eater (Also obvious).
7. Honored Mom/Dad (Tommy scored two goals!)

Readers added their own, including the Facebooker who never updates their status — The Observer or The Lurker. Others pointed out inept marketers who don’t know how to use the site. (Of course, one marketer couldn’t resist plugging his own site.)

Peter has inspired me to work on my own lists for Twitter and LinkedIn personality categories. Your ideas are welcome.

Here’s just a few for each site to get started. Moving forward, we’ll certainly focus on more than just the clever putdowns, even if they are more fun.

Twitter:

• The Strafer. The user who can’t resist five or more tweets at the same time. Guess they think that this is effective marketing. I call it hit the Unfollow button.
• No-Free Lunchmate. The marketer who plugs “free” things, which invariably cost something, at minimum your e-mail address.
• The Forgetful. The user who teases the same content constantly — usually their own.

LinkedIn:

• The Conversational Spammer. The user who turns every appearance in a Group, Ask A Question, or Answer A Question into a pitch for his services.
• The Expert’s Expert: The user who spends as much time calling themself an expert as he/she does communicating on the site.
• The Forgetful. See Twitter above.

Again, we’d love to hear your suggestions. Yes, you’ll find teases to this post on Facebook, Twitter and LinkedIn, but notice the lack of spam or any sales pitch.

There’s a name for that category in social media, too. It’s called: The Rarity.
