100% agree - that was why it has been an open marketplace up till now. It's incredibly hard to predict what will and won't sell. However some we know for a fact won't sell for a variety of reasons. Right now ~50% of products don't sell. Can we lower that rate? I think so..
The sort we use now does hide these products very well (which is why most people don't get into the depths of Tindie). I'm also not opposed to a user rating system - we have had one before. I'm sure we'll have another one down the road.
It's just clear there is a lot we can (and should do) to better the experience for customers and sellers alike.
(BTW this is totally a discussion we should have. Apologies if I sound like a scrooge - ate a bad burrito for lunch and have been paying the price this afternoon. Don't go to the place near our office. )
