As much as I tend to see this whole thing from the sellers point of view, I think eBay's problem is that they are losing buyers. All the moves they've come up with in the past couple years are targeted at buyers so they can say, "Come Back, it's safe to buy on eBay."
The problem with this is that many buyers are in fact sellers as well. Who here only sells on eBay, but doesn't buy as well? Buy making it easier for people to sign up and become sellers, many of these new sellers will become buyers as well.
I have been selling on eBay for a long time, and I have seen a lot of negative changes along the way. The biggest of these changes was when eBay and Google got in a spat of some type or another, and eBay stopped paying for higher visibility results. Before this happened, if someone did a search for a particular camera, my eBay store came up at the top of the search results. After the change, the eBay results were pushed lower, my items were mixed in with everyone else's, and my store not mentioned at all, this caused a near 90% drop in my traffic. I pay extra money for an eBay store so I can get increased visibility. If there is no increased visibility, what is the point?
Next, getting help with selling issues at eBay is next to impossible. I have spent hours on the phone trying to resolve common issues. In the past, eBay assigned a personal representative to higher-volume sellers, whom I could call and talk to directly. They no longer provide this service, and many problems simply remain unresolved. I can't call anyone, I have to submit a question, receive a one-time phone number and code, call and wait on hold, then talk to someone who can't help me. If I ask for someone to call me back, they say they will, but never do.
And there are bugs on the site which remain unfixed. I can no longer link my credit card to my account. I go to the menu to set update my credit card info, which has all the proper fields. I live in Japan, so I select "Japan" from the drop-down menu, press "next", and then am told that my zip code is not recognised. Since I am in Japan, I have no zip code, pushing "next" seems to revert the form to the default US setting. If this problem is widespread, and exists in other countries, it is major issue. But this problem has existed for more than a year. I contacted eBay about this, they walked through the problem, and said "gee, that's not supposed to happen", and have done nothing about it.
I hate to see eBay going on like this, it is as though the company were being run by a bunch of senile idiots.
