First of all:
Further restrictions on vending would mean having to find more uses for Wizard Tokens such as a lot of new items in the Token Shop and more frequent restocks
has stated multiple times that TS restocks are going to be weekly. (pinging you so you can confirm)
But to get onto your OP, which I really just disagree with all over the board:
What makes it worse is that so many new restockable items are Super Rare because the chances of them ever coming in are next to zero.
Nope. THREE of the new horns are super rares. ONE of the new Cavern of Curios foods. ONE of the new chibi stickers. ZERO of the new seedlings wearables. ONE of the new lace shirts (none of the dresses) THREE of all the new glade items (plushies, beanbags, and lollies)
So out of 58 new items (excluding SubQ because that is a different level of restocking) 15% are super rares. That is not a lot. Should everything be easy to restock? No. Because /that/ would ruin the economy.
Vending - most of the items are the same worthless junk that restocks in the NPC shops.
Would you like to vend collection items? Super rares? Subq? That would also ruin the economy. If you don't like the junk you get, you can frag it. Sell the crystals for 5k a pop.
Quests - most quest prizes are the same worthless junk that vends or restocks in the NPC shops.
Again, would you like monthly collection items and subq? Frankly, I get really nice items from Alex and Maleria, and occasionally Pete and Mori/Nori. I now get a mage amulet every 1 in 3 quests from Quentin. Not to mention the sP rewards??? Again, if you don't like the items, you can frag the worthless stuff and sell the things you can profit from (there are, because I do it).
The only thing I can literally agree with here is: Restocking is broken (code-wise) and Where are our sP sinks (thanks )
Where are our SP sinks?
I was going to post this instead, but that one's good too:

I suppose my views are coloured by the fact that I remember what it was like before vending machines were invented. I'm not the only person who thinks vending is really bad for the economy. As restocks are broken at the moment, though, it's currently the only way of getting some items on the site such as over inflated food items and books.
And more items would be nice if we didn't have vending. But, again, my views are coloured by being here in the days before vending. We got our NPC shop items from quests and restocking. Of course, we didn't have so many items on the site then so that probably has a lot to do with it.
I don't know where you've been for the past few months, but foods and books have been inflated far before restocking was broken. Without vending, they'd just be worse.
Vending is how I get crystals. I like the 100sP items. I like when rares are below 4k sP. I would rather not see humming power crystals inflate because it's harder to get crystals.
Battling > everything else for once? I can't complain. xD
It's also tough cause it doesn't sound like there's anyone else that's able to take over things like the restocking system, quests, etc., while Keith works on the battle stuff. -shrugs- :/

Where are our SP sinks?
I was going to post this instead, but that one's good too:

So here's an interesting question. Why have many books been inflated even though they can be obtained through vending? Is it possible that there are so many books in the Book Nook now that the restocking system couldn't cope with them even before it became broken?
The problem is that would be fine for users who have been here for a long time, but you can't curb things across the board when there are new users who don't have any sP to begin with.
"Working" on restocking means taking the system I rewrote and tweaking a few things here or there. Also I'm seeing plenty of R80+ items that have restocked over the past two weeks in the new restocking system?
And finally, the sP sink shop is coming sooner rather than later. We changed our approach from the initial board, and are making sure that if we put some particular items in there for a few billion sP it won't break anything :)

Books have been inflated because 1) They're books. 2) Have you seen the books that are inflated? Apart from Super rares, they are Normals. Normals should NOT be inflated, but they are because Alex asks for them, and as we all know, Alex gives hella good prizes.
That is why they are inflated. Also, they introduced beanbags to Blue Sky. Beanbags vend way more than books. Books inflate, beanbags deflate. Fact.
I've been around here a loooong time too. My memory is at variance with yours.
I remember what it was like BV (before vending), and prices were outrageously high in 2006-sP. Remembering at those prices vs how sP is in 2015 someone might miss that. Also if I restocked anything at all before the site crashed (, not just a random book to add to your total-read) or someones else grabbed everything in the shop, you were lucky. If I hadn't belonged to a guild on Neopets that supported me as a newbie here I'd have been utterlyfucked. At the time everyone was recommending Item Hunt, and I just couldn't come up with the sP to play the game and more often than not it was NOT profitable. The system you remember was hard on new guys.
The Subeta economy is smallish and it is not homogeneous or efficient because not everyone restocks/vends/quests at the optimal point. There aren't enough users regularly playing and doing all of these things for the errors individuals make to average out. Right now, there's not so many folk restocking in Books and more people seem to be doing Alexander lately (I think he sucks so shrug, but then I don't much like questing). Vending is limited, so even if everyone restocked Blue Sky, not so many books are added as could have been based on profitability of vending books. Restocker that do stock there try to get what they can. No competition from vending and other restockers result: higher priced books. IMO this is entirely due to player-action or -inaction and has nothing to do with how the economy is being managed by staff.
