Your fees contribute to eBay’s ability to significantly invest in the overall experience for both sellers and buyers.  Enhancements on the buyer side of the equation are aimed squarely at driving traffic to your listings and ensuring the 7.3 million Australians who visit the site every month continue to do so. For example, investments in marketing, social media promotions and mobile commerce applications helped sellers to capture a greater share of online sales in 2012 and saw a 21% year on year increase of visits to eBay. After reviewing the changes it should be clear that the new fee structure also encourages sellers to adopt the behaviours that we know buyers increasingly prefer (eg: fixed price over auction in some categories) – therefore increasing your chances of a successful sale.

I didn't pay much attention to this post yesterday, but now that I've read it through, and with the actual effect of fee changes etc completely aside...

Enhancements like off-site, 3rd party competitor's advertising all over eBay and on individual listings? Like on-site competitor's advertising in listings and seller emails? These aren't things that drive traffic to (individual) listings, they are things that are purely intended to drive traffic away. Or, are the (overall) increased fees finally going to get rid of all that advertising. That would certainly enhance the site. Or maybe we'll finally get a cart system here, or the mobile app glitches will actually be fixed. I think most people would really like one of those things more than a Pinterest button or little stars next to the 'Wish List'.

In that case, I guess I'll stop seeing the "want more exposure? try auctions!" note when I end BIN listings - of course, it would never occur to a seller to adopt behaviours their buyers prefer,  I'm sure most sellers running auctions consistently do so because it never actually works for their business. You don't have to make auctions more expensive to discourage them - market trends have a tendency to do that all on their own. 

Good grief, I think I'd much rather an introductory post that went a little something like...

We're changing fees (insert link to new fees). Get used to it.
