Just a quick observation totally unrelated to anything...
I was just noticing on other collector blogs how despite the content, photos, etc. on a blog post, most people get between 3-5 comments each time they send something. If you are me, it's usually less. But overall, the average is probably somewhere in that range.
But you offer up a contest???....And the dam breaks.
Instantly your comment count increases 15-20. Make it a FREE contest and that number immediately goes to near 50 or more.
The moral of this story...CARD COLLECTORS LIKE FREE STUFF!!
