This entire thread was particularly frustrating to read. I absolutely agree with many of the points here. The new UI is terrible and even as a buyer (which I am very often), it isn't appealing at all.
However, what is particularly frustrating above all is the admin's decision to ignore everybody's criticisms here in lieu of a buyer's experience when the admin is most likely not a buyer themselves.
The old design may have looked a little cluttered, sure, but it offered plenty of valuable information. The "Buying" and "Selling" tags were useful for me while I was scrolling through the forum list. I could see what was for sale or what it was that people wanted. The fact that both of the tags were in different colors made it easier on the eyes. Not to mention, I liked to sort by "Bought" and "Sold" because sometimes those threads would contain valuable information and help me gauge the price of what I'm buying or selling.
As others have said, there's a lot of dead space in the middle of the forum list. I personally think the text being so close to the left margin is incredibly visually unappealing, even on my phone, and it feels particularly empty. The lack of colors (besides the colored threads themselves) from the absence of the "Buying" and "Selling" tags, as well as the avatars being moved to the right side, is very unaesthetic.
And if you are going to argue that buyers can add "WTB" to their threads, then consider making thread lengths longer and with fewer limitations. You're making users waste an extra three letters in their titles.
I still don't know who decided that tags, views, creation dates, and last replies were considered "not so useful information", but I and many other people seem to think differently. If you think I am wrong, then perhaps you should consider hosting a poll so that even lurkers who don't wish to post their opinion can have a say in which design they prefer.
Please don't handwave these opinion posts away and decide what you think is best for the "buyer experience" on your own. Even if I end up being horribly wrong and people think otherwise, at least make a proper effort to listen to the loyal users that use EpicNPC regularly.
Most importantly, I daresay many of the buyers on EpicNPC are lurkers. A large number of them probably don't even have an EpicNPC account, or if they do, they are only using it to buy one or two things once in a blue moon. They're not the ones using your forum the most. It's the sellers. They are the ones spending money on thread upgrades like auto-bumping, stickies, thread glows, ads, etc. They are the ones spending time dolling up their threads and making sure it's presentable to the buyers. They are the ones actually USING the forum the most.
EDIT: I would like to acknowledge that I do see [Sold] and [Bought] tags on threads, so it is my fault for assuming they were gone like the other tags. I still do think they would look better like how it was in the old UI though.
