No. Do not use paypal as an intermediary for BTC. Ever.
Super risky. People want to get in on the action of bitcoin, but not open any additional financial accounts. They need to figure out how to get paid in bitcoin for mowing lawns or something. Then the ball will really be rolling.
BTW, i found this little game for growing BTC. Just started a couple days ago myself, so I don't know how well it works. But it's worth a btc to find out. http://fxnet.bitlex.org/?ref=1139
