The late Sarah Peller, (in)famous for the line in the title, nailed it. When you want something of substance, you ask for it.
I just posted a blog entry over at eBay - you'll probably see it in my eBay blog links on the left. In it, I was asking for feedback (but avoid using that word in eBay blogs - you get a lot of comments about EBAY feedback, which is a touchy subject to many) on two listings I am testing through Sunday.
The silence was deafening. IMNSHO, most bloggers over there are social animals, beggars for bids or compleat lunatics. The notion that I would ask a marketing question to a bunch of marketers and buyers and get NOTHING is telling.
Perhaps postcards2go will notice and respond to that and this.
[Sigh]
