Dude $5! for your skunkworks? bah! I would give $5 worth of info away just to be nice.. Hell I think I have given away better info than that and was worth a lot more. I remember being at the bar sipping on a drink and telling a heating and air guy to link link link link link and he would get great traffic in no time.. I think that info was worth thousands and we all share it for free everyday.
Now I could see if you had like 3 or 5 other ways to get traffic then it would be worth the money to spend. In that case I would give one away to sell the rest but thats just me.
