There's a new Uber competetor being built on Solana with a token of course ๐คฆโโ๏ธ. Never the less, it looks interesting and is something that certainly could be built on Nostr instead.
Maybe worth keeping an eye on https://guides.trip.dev/
I still maintain that alot of the recent issues around clients only reading from the top 5 relays would be alleviated by having http relay. Managing WebSocket subscriptions is a pain, I'd much rather just shoot out http requests to the different relays that a one off note may be found in.
Just like a website could show 100 images from different domains, we can fetch 100 notes from different relays with http reqs. I don't believe the narrative that http relays would impair client perf.
