I just did a giveaway on Poloniex.  Just said that I've got 500 SILK to the next 5 people who post an address in the next 5 minutes.

People loved it, of course. 

I figure it's only costing me a buck or so a person, and one in every so many of them will look us up and cross over to the silky side.  Will probably repeat another day.  Keepin' crypto fun
