I have seen too many people being hyped about it when it first came out, but then slowly overtime it became a lot less interesting and that caused it to be a bit more bland. That's of course with every hype, it becomes very much liked at the start but then slowly it got a lot carried away with time and should be considered a bit different.
That's the problem. Hype is what kills promising projects in the long run. Decentralized domain names hold promise to make websites resistant against government censorship. If only developers put them to good use, things would've been different now.
So far, decentralized names have been used for NFTs. ENS and Unstoppable Domains seem to be the most popular services right now. There was Namecoin-based domains (ending in .bit), but I believe the project is nothing but dead. A pity because this, combined with decentralized CDNs (eg: IPFS) would've made the internet a better place. Maybe someday, right?
