Kari was not gonna take Quad's comments lying down. She decided to fire back with an un-inviation text that asked Quad to start "acting like a doctor's wife instead of a low-class whore." Those are fighting words, Kari!

MJ decided bring up scandalous pictures that Lilly posted online wearing nothing but her pooch Coconut on her chest. This swimgerie designer doesn't see anything wrong, but the topic made for an tense dinner.

Poor Joanna. Her suspicions of Romain's fidelity were confirmed when she found incriminating emails where he was professing his love to another woman.

When Jax went on the rebound with fellow SUR staffer Laura-Leigh, Stassi was not going to take it sitting down. At least not without sending some pretty nasty texts: "you are pathetic, have zero self esteem, and meant nothing to anyone...welcome to the world with no friends." #ouch

Brandi decided the best way to offer Marisa some marriage advice was through text message. The advice? Give each other a hall pass. This was the text heard round Beverly Hills that started all the drama for Lisa's vow renewal.

Before there was Twitter, Facebook, or any other social savvy start-up, there were texts. And sometimes things got rough. . . like the time Kim Zolciak called NeNe Leakes a low budget bitch.

Whether you write your own blogs or you have a ghostwriter handle your media presence for you, Lauren Manzo believes you should be able to spell the content. Got that Teresa?

Bethenny Frankel found out the power of the blog when she realized Perez Hilton reported her pregnancy announcement -- before she and Jason told his parents.

Miss NeNe is always good for one-liners. We'll never forget the Season 4 Reunion's battle-cry: "Check my timeline!" Seriously, check her timeline, she swears she's clean.

In the midst of wedding planning, Kim learned an important lesson about Twitter etiquette. If you aren't going to invite your mother to the food tasting, don't tweet a photo of you at the food tasting. She will find out.

Everybody knows that Twitter is all about speed, which is why Adriana was so miffed that Karent got her 140 characters out faster, coining the insta-hit line "She beat me to the tweet!"

Note: don't send threatening emails, particularly not to Kelly Bensimon.

Adriana re-tweeted a claim that Joanna Krupa had been an escort, and discussed the allegations on WWHL. . .by discussed, we mean got into a heated arguemeent with the supermodel.
