My main gripe with Discord is the somewhat ephemeral nature of it, due to the search being horrible, as well as not publicly indexed nor easily accessible without an account + an invite to a specific server.
The blue tint disrupts your sleep cycle and helps keep you awake when driving at night. There's definitely a trade off to be had depending on where these lights are located though.
It is very nice not having to write code from scratch by hand, but I have noticed that by not doing so, my innate familiarity of the code absolutely craters. Making manual changes to the code suddenly becomes a much more tedious and less confident process, and in many cases I am not sure that it's a net benefit (at least in a situation like mine, where there is no oversight and things go straight to prod.)
It would be nice if any of these sites had an AR solution that was completely clientside. I can't bring myself to agree to let them store my face + face info for 3 years.
IIRC iPhones are supported, you just will only have access to the T-Mobile network. That and having to re-enter APN settings on every system upgrade are the only constraints from what I remember.
