> It pollutes the global namespace
I think we should rely less on global namespaces. DNS was designed in a way that specifically allows for the same name to mean different things for different people. I should be able to use my first name as a domain name if I want. Other people should also be able to use their first name if they want. Other people still should be able to use whatever domain they want to disambiguate between the two. This is a feature of all high level programming languages within a rounding error.
> it's hard to search for
It was the first result for me on Kagi when I searched "video lang". I also tested Google and DDG and unfortunately it didn't even make the first page. I wonder why Kagi was able to surface it, but not the other two.
Either way, I recommend using search engines for discovery rather than recall, and you've already discovered this through other means. For recall, save a link to it. I personally use Org Roam for capture and recall.
> I had a hard time making someone install "Signal" at a stressing time because that's just a normal word in French.
The English word comes from the French word[0], but as an English speaker at least, the name makes a lot of sense to me. Particularly, it is a descriptive name that to me doesn't feel super generic like video lang.
