I do..especially if i see people with a very small new pup. Its much better here than looking through a book and not getting anywhere. I think real life stories from experienced yorkie owners is a much better way to learn.
 
While i'm chatting,I also talk a lot about Poppy, my little puppy farm survivor, and her past life, to try and stop people buying dogs from pet stores.
I will be getting a reputation and people will be crossing the road to avoid me, although i don't preach, i do it in a nice way!!...lol
