Just to get different answers from people. So many like to give snarky or wired answers and it opens the door for some of them. Sometimes a question is just for fun.
I think perhaps they think it is fun to get us all googling at the same time 8=)
They do it for the other people that are on here. To give them something to think about and comment on. Keep it up kids.
How is Googling cheating? It's using the materials legally available! Plus, I learn stuff here too.
Maybe it's to do with getting an answer out of experience rather than formality. Or hearing opinions.
Google only gives you one, factual answer.
Sometimes the answers are hilarious , and it gives us something to do.
