Is texting/tweeting the same type of crutch as smoking/drinking/taking drugs? It is used to help people get through life. Are they hobbled without their crutches? Why ?

I consider texting as a solid form of communication, sometimes you just can't make a phone call. Tweeting is something different, it's not the same. I have a Twitter account but rarely use it. 

I actually don't know anyone who tweets. That's because I hang around intelligent people.
