wich is better mailing list or usenet newsgroup

[Linux for blind general discussion]

I can't speak to the whole newsgroup thing myself, as I never figured 
out how exactly it was supposed to work. I do understand email and the 
web however, so these are my go-to resources when looking for 
information of any kind. The email list is probably the best option, as 
I just subscribe to the lists I want, and I see everything posted to the 
list. If I don't want to read a thread, i.e. if it's not a topic of 
interest to me, my email program allows me to delete the whole thread 
from my mailbox at the press of a single key, leaving everyone else's 
copies untouched. Those lists that store archives are especially good, 
since just like a web forum, I have the option of searching through 
previous postings, even those I have deleted, in case something came up 
that I need to find again. Usually a simple Searx will give me the 
answer from the archive, so I don't even have to try to find the archive 
website for each list. As I understand it, newsgroups are not archived 
on the web, and from what I could understand of their functionality, 
seem to be pretty much walled off from the rest of the internet, making 
usenet rather useless to me personally, unless I'm totally wrong about 
how it works.
