Not More Than 50

I agree with some of what is written here, I think once you go above a certain number it does become impossible. Some people have 500 to 1,000 people in there's it seems ridiculous to have that many "friends". I think once you get above 30 it becomes tricky.

Its just impossible to stay in contact with a large caball of people who don't really know. So called friend collectors come to mind.
