Do you think it could be useful for a bulk buy and sell site?
Consider the following, since the site is made with the limitations of PoE in mind, you can put up bulk buy and sell orders like in tft, but you make the original message directly through the site. With that, you can mark someone as 'busy' when they accept until they close the bulk trade, show how many active offers have been made, get reports on how often someone responds to their bulk requests, etc.
Essentially, by removing the fire-forget-floodgate setup that something like a discord server or the official tradesite have, participants in the bulk trade site imply that they're ready to trade and that your trades will actually go through. You can see if you're the 90th person to message for a bulk sale that minute and if you're the first to message, you're the first to actually be seen.
I've seen rumors that api leaks have indicated that the new thing will be tipping posts directly.
Which is EXACTLY what that site needs - repost bots being financially incentivesed. I guess that's one way to get your usage back - Reddit started as just two dudes posting links to each other and will end as ten thousand bots reposting those links.
