The thing that may be causing this slight decline in terms of interests about NFTs is the current market conditions which is bad and got worse many days after you created this thread. Another factor maybe unawareness of other NFT markets other than opensea which offers a wide variety of good NFTs as well and has much cheaper prices and fees due to the low fees that are required for every transaction. Still though, my twitter notifs still continue to explode due to NFT related tweets and retweets. I guess the drop on interest isn't really that drastic.
