Is it appropriate to distribute stacks of business cards at a networking event or conference?

I don't distribute stacks of business cards at a networking event or conferencing. In fact I go to a lot of conferences and business meetings and if there's a circle of people around a table that put their business cards in a stack and pass them around I don't enter into that practise. When I get home and I find all of those business cards of people that I don't remember, I throw them away. If I don't have a human connection with someone the business card has little value. So I never let a card leave my custody, between me and the person who's going to receive it.
