Archiving newsgroups and mailing-lists is not a new idea, and we were not the first site starting doing it.
Furthermore I don’t claim that derkeiler.com is the best newsgroup and mailing-list archive.
You as a visitor should choose which site best fits your needs.
Here are some other established sites:
|Google Groups||The biggest usenet archive (was deja.com)|
|MARC||A very big mailing list archive|
|Seclists.org||A Security mailing list archive from the creator of nmap|
|Neohapsis Archives||Another established security mailing lists archive|
