NGL . . . I understand PoW but I don't understand how some nostr clients like nostrudel are using it.

1. Not all clients use PoW

2. Some that do don't have feedback that you did (Poster UX)

3. Some clients don't show PoW scores to anyone (Reader UX)

4. PoW isn't using my CPU/GPU power (that I can tell) so where is the 'work' coming from?

I think PoW on notes should be a standard to limit spam but since I clearly have no idea what's at play here then it doesn't make any sense so if someone can help me out it'd be appreciated.
