When Google Groups acquired Dejanews
https://en.wikipedia.org/wiki/Google_Groups things looked promising since we now had a good web browser interface to newsgroup postings.
The following points bear mention:
(1) Newsgroups are based on an IETF standard http://datatracker.ietf.org/doc/html/rfc977 so anyone can provide a server and anyone can write a newsgroup reader.
(2) Embedding a Newsgroup in a Web page is (was) a great way to add a standards-based discussion forum to a Website where the forum GUI was maintained by Google and had all the advantages of NNTP (but see (8) below)
(3) Almost all email readers (used to) include a newsgroup reader
(4) A newsgroup is JUST like email (except that it is *TO* the group, not to an individual email)
(5) A newsgroup is self-archiving (a new reader is able to see all posts back to beginning -- note how if you CC someone a normal email, they have no ability per se to see previous posts in the thread - but with newsgroup threads they do)
(6) When posting TO a newsgroup, one can add CC and BCC to assure the post goes to individuals' email addresses
(7) One can *link* to newsgroups postings. The URL looks like this:
(8) Embedding a newsgroup in a Web page had one fatal flaw
Several years ago I attended a Google I/O conference (an annual event for developers) for the sole purpose of finding someone at Google who could explain to me how to fix a bug in embedded Google Groups, When I embedded a group into my Web site in order to instantly have a fully functioning discussion forum everything worked fine EXCEPT that if someone was not yet logged in to the google group the google group GUI would display a login in a pop-out page. Once the user then logged in, they would see the googlegroups GUI but in a new window, breaking the embedding in my Web site. That essentially trashed the goal of adding a forum to a Web site by using an embedded GoogleGroup.
I pushed a bit and found one Google engineer who told me that there were some kind of security risks so they were forced to show the GoogleGroups login in a separate page. I could not figure out how to get back to my page embedding the group once the login succeeded (since I had no control over the popped up Google login page HTML or javascript).
Later on Google entirely removed the ability to embed a google group. See: https://oceanpark.com/socialweb.html.
FINAL REMARKS
I believe newsgroups are still one of the best internet technologies whose time is yet to come (in spite of being over 40 years old). Newsgroups are truly social media in a way that the owned so-called "social" media are not and never will be. We can hope that the vestiges of USENET will survive and perhaps new RFCs be written to enhance security and durability of newsgroups going forward.
