Technology makes people dumb.

"Texting is apocalyptic on some level. It's a reduction of things." -Nick Cave 

“OMG”, “LOL”, and “IMHO” aren’t just Internet jokes, but ways that people today are legitimately communicating with one another. With the speed of emails and texting, users have become increasingly impatient with full sentences, leading to “G2G” instead of “I’ve got to go now.” The ease of this language is easy to see. In the middle of a busy day, or if you’re sneaking in a quick message at stoplights, it’s far more convenient to fire off a couple of letters rather than worry about scripting and punctuating an entire sentence. But what does this convenience mean for the state of our language skills?

Texting, in its nature, shuns grammar. To get out a message as fast as possible, people will lose punctuation,
sentence structure, and capitalization. Run-ons are as common as fragments. For those with phones that auto-correct, even spelling can be ignored because the phone does all the work. While this shortened language allows users to type more quickly via text messages, instant messages and social networks, students are increasingly having trouble switching back to traditional grammar when necessary.

Using text language while texting doesn’t necessarily mean a person doesn’t know any better; it’s a language of convenience. But those who are still learning, or who become unable to separate it from other activities, create the danger. Texting is simple, casual, and tends to be vernacular – something that can be spoken on the street. When this gets applied to emails, schoolwork, and business situations, a problem arises. The casual tone of texting can be misconstrued, and is generally considered not very professional.

I've been using my phone since I was in elementary. It didn't really affect that much of my English fluency because I don't really like to shorten words or make them in "Jejemon style." Another reason is that I think my hobby of reading a lot of books helps me maintain my English fluency. I think texting even helps me improve my English fluency because I will always be cautious of my grammar and my use of punctuation marks. There are times when I'm too lazy to type a reply, I tend to shorten words. But I don't think I'm stupid enough to let those words diminish my knowledge and fluency in English grammar.
