Just on the message-reply bit...

Gmane.org carries this list (among many), archiving the posts with both 
nntp/news and http/web interfaces.  Both the web and news interfaces 
normally allow replies to both old and current messages via the gmane 
gateway forwarding to the list, tho the first time you reply to a list 
via gmane, it'll respond with a confirmation to the email address you 
used, requiring you to reply to that before forwarding the mail on to the 
list.  If you don't reply within a week, the message is dropped.  
However, at least for the news interface (not sure about the web 
interface), you only have to confirm for a particular list/newsgroup 
once, after that, it forwards to the list without further confirmations.

That's how I follow all my lists, reading and replying to them as 
newsgroups via the gmane list2news interface.

http://gmane.org for more info.

The one caveat is that while on a lot of lists replies to the list only 
is the norm, on the Linux kernel and vger.kernel.org hosted lists 
(including this one), replying to all, list and previous posters, is the 
norm, and I'm not sure if the web interface allows that.  On the news 
interface it of course depends on your news client -- mine is more 
adapted to news than mail, and while it allows forwarding to your normal 
mail client for the mail side, normal followups are to news only, and 
it's not easy to reply to all, so I generally reply to list (as 
newsgroup) only, unless a poster specifically requests to be CCed on 
replies.
