Yeah. What happened was that some offer had been deleted. The person offering reverted the deletion in a bit heavy-handed way and with this all additions of the 5 days before.
I've inserted these entries again on July 2th, therefore the number jumped up again.
Anyway, if that growth rate of number of entries is related to real trade (a big if), and it could be sustained for a year or two, this would become a remarkable market place.
But what kind of items are sold successfully? I made a page with photographs for my friend (she creates awesome images) but so far, nobody has bought for bitcoin. And I'd say this can be a really excellent way to sell things like photographs and music.
OTOH, there needs to be a point of intersection of people who are 1) technically savy, 2) have good and interesting offers, and people which 3) are technically savy as well and 4) have the money to afford these things. Selling art for income isn't easy.
Could you collect some hints for merchants, artists and creative people? What are your experiences?
