Good article, but few read the RG. 
For enforcement folks, we see that there is a wide degree of latitude in how officers apply the law. Only 17 tickets issued so far indicates to me that of the total infractions, it's a drop in the bucket. And then there are judges, some of whom will reduce the fine for first offense or mitigating circumstances. What would an officer do if someone later injured or killed someone while texting?  I am inclined to issue more tickets and let the judge make the call.
For anyone caught lying about it, that is an immediate ticket. These people know.
I sent a text to a friend that returned an automated text saying that she was driving and would reply later. That is a great app.
Guessing, I'd say half the drivers think it is OK to text at a light. You can see many furtively texting, and some are the ones in front of you that seem to not notice the light. I'd add a few signs at street lights that read: "Distracted driving laws apply while stopped at light."
