"Texting, Tweeting, or emailing is a brilliant way to miscommunicate how you feel; and misinterpret what other people mean."
You've been there before. You send a message to someone, then you wait. They finally reply two hours later, totally missing your point. Now you respond trying to remake your point, but also responding to your interpretation of what the other person said. Pretty soon there are three or four subconversations happening on top you correcting yourselves and you can't see a way out of this. You decide it's easier to have a phone conversation to clear things up.
You may also have had a small conversation about money - perhaps the credit card bill came. Then before you know it - and you have no idea how you got there - but you are in a shouting match with your partner. It seems that small money conversation was like an electric fence you didn't know was electric*.
Imagine if you will what would happen if you combine these two situations. You attempt to have a conversation about money over text (or email or any other text-based app). Things can - and usually do - get out of control in a hurry. Everything gets miscommunicated. Nobody understands what anyone is trying to say. Everyone has different values and nobody knows how to articulate that in a message.
It's best to save conversations about money for times you can actually talk in-person (I include Skype, FaceTime, and other video call methods in the definition of "in-person").

Conversations: Your Words
Texting, and it's cousins emailing, messaging, commenting on social media, writing letters (does anyone remember what that means?), contain the words you are trying to communicate.
Admittedly, using the wrong words can get you in trouble if the reader knows better (I'm talking to you, people who say "less" when you should say "fewer"). Unfortunately, there's no credit for using the perfect words. The actual words you use make up only about 7% of the meaning you are trying to convey.
When you communicate with email, text, and other messaging apps, less than a tenth of your message is being sent. That leaves a lot of room for your message to be misinterpreted.
