Edit: After posting this @friendlymoose replied and reminded me that @leprechaun is running proofofbrain.blog. It doesn't have the Outpost layout of proofofbrain.io but it works just as flawlessly. The POB NFTS can be accessed through https://tribaldex.com/openhive/collections/POB. So I guess not all is as lost as I originally thought.
I've been monitoring the proofofbrain.io domain WHOIS record and it's not looking promising. Unless the individual responsible for proofofbrain.io renews the domain within a day it will expire. Without a registered domain the proofofbrain.io site will likely vanish permanently.

Of course, the basics of POB will continue to exist on the Hive blockchain. Posts using the POB tribe tag(s) will still appear on other Web3 sites connected to the blockchain such as peakd.com. Users will still be able to post using the tags and curate content. The Proof of Brain Hive Mind community connected to proofofbrain.io will still exist.
I have POB staked in my accounts and my alternate @holovision.cash account is providing some liquidity to the three POB diesel pools on tribaldex.com. I think I'm just going to continue to hodl, whether or not POB has a front-end website. We may never see the price of one POB token equal to one SWAP.HIVE or above as it was when POB first launched. However, I am optimistic that POB could reach 0.1 SWAP.HIVE sooner or later.
The bell may toll for proofofbrain.io on February 25, 2024 at 21:22:16 GMT. After that who knows? If the @friendlymoose POBphotocontest rounds continue I will consider that a good sign that the POB community is remaining active.
