The archives of the SC mailing lists (sc-users, sc-dev), hosted at the University of Birmingham, are an excellent resource for learning about SC and getting inspired. They include data from 2002 onwards. Unfortunately, the search for years before the current year is a bit difficult to find.
Either go here to choose a specific year, then the search via the htDig icon will include the whole archive:
To explain it for newer users: years ago there existed a mirror of these archives on nabble, which, due to regulations, couldn’t be kept. There were long discussions about this (which you could also find somewhere).
However, it’s great that the original archive is there. I suppose it’s not heavily used now, many people don’t know it, or they don’t know how to search for elder threads.
I just recently ripped an old music blog that I used to love (most of the music was still online, surprisingly!) - I can confirm that SiteSucker does a great job at this, well worth the $5.
