I have something that due to the niche of the product, makes it very hard to sell to anywhere BUT eBay. There are a lot of attempted alternatives in this niche but none provide the instant kind of payment you'd get from using eBay or have the quantity of buyers. It is truly the network effect at work.
What's my point about this? It's that the problem with eBay isn't because it doesn't have a Pinterest-esque style layout. No one really cares about eBay's dotcom style layout, or the fact that it the logo until recently was schizophrenic about it's capitalization. It's because they completely bone the sellers. If you're a seller on eBay, you're constantly juiced on every little single thing. You also have little recourse if a buyer rates you poorly (I guess punish him back by rating him badly too?). It's been a slow methodical shakedown of sellers and quite frankly people are sick of being nickel and dimed to death. So I hope this blows up in their face and that they continue to lose market and mindshare.
And I find it funny that eBay is now promoting that images are the way to go with this layout when for years they nickel and dimed sellers on photos (Is the max 3 without paying? I forget) and the photo quality of those images was always terrible, like someone set JPG compression to 50%
