who is using uber h3 and what for? (besides uber of course)

As one example, the U.S. Federal Communications Commission uses it in its Broadband Data Collection program. You can see some of how it's been implemented here: https://broadbandmap.fcc.gov/ Edit: It seems some people get a blocked message when visiting the base url. The home path may work better? https://broadbandmap.fcc.gov/home

I cannot... Geoblockig European IPs?

I never understood why anyone would prefer the H3 hex tiles over Google’s much simpler S2 system: http://s2geometry.io/

Sure, hex tiles make certain circular nearest neighbour searches slightly more accurate… but still have an error.

And then… everything else that’s inconvenient with hex tiling, like that issue that subdivisions of a cell leak into the neighbouring cells and hence don’t add up to 100% of the parent! This makes many database queries return lies, or the queries need very complex and slow(!) code to compensate.

I’ve used h3 for a game. Since they align with an unique hex, I can ensure that one cell grid aligns and is placed on the same place in the world, where players could then compete on.

That's really neat. Here's a screenshot for people who can't access that URL: https://gist.github.com/simonw/eb31ec34af16a1e19ee0d7ca90e8a...

amo is using it quite a lot, mainly for the scratch map feature in the Bump Map application, but not only.

Use cases are: - data storage - data aggregation/clustering - spatial indexing - geometrical computation (as long as you're OK with approximation, you can speed up a lot of things by working with CellID instead of actual geometries) - data visualization

I've seen it used by Databend, Helium, Breakroom (they did an Erlang binding on top of h3o), beaconDB, Greptime, Meilisearch. But I don't exactly know what they are using it for (just that they pulled h3o in their projects).

H3 was integrated into ClickHouse in 2019, and since then, I have heard many interesting stories. There are unusual ones, e.g., when it is used not to map data on Earth, but for astronomy (stars, galaxies).

I'm curious about those interesting stories ^^ Care to share a bit more?
