Why do Christians on facebook write thank God for,,,,,,,, on their facebook page?

[Gino]

I had a friend on facebook who would thank God for something every day on facebook. Today she wrote, I thank God for all the struggles I've faced because without those struggles I would have not become a better person. So I wrote on her facebook on how stupid that sounded. God doesn't want us to struggle. Plus why are you thanking him online anyway?
Instead of answering my question, she removed me from her friends list. Which doesn't bother me since I think anyone who is writing thank you God for anything online, isn't all there from the get go. I thank God all the time but I don't have to advertise it for the whole world to see.
I thank God that I didn't take a dump in my drawers this morning. So Christians, why advertise your, thank God on facebook?
