Evolution of Texting

There was a time when messages were just a simple, short pieces of Information used to convey a message. For example consider this:

Hello

Hiee

How are you ?

I'm fine.

Can we Meet ?

Okay !

Here, the messages are short & precise. But over years people started putting more to it than just short messages. People started letting their emotions into it, Lets say becoming more humane rather than sounding like a robot. Now people text like this:

Hello..

Hiee..

How are You ?

umm... I'm fine !

Can we meet ?

Yeah, Sure ! :)

by Humane i mean people started being more informal in their texts, I don't know if its comfortable that people look into when texting someone or is it just laziness ? But this evolution from Simple & precise to nowadays texts filled with emoticons has seen major growth. The sole purpose of emoticons was to fill this void, isn't that right ?
