I'm personally archiving some of the great content from my community on Reddit because it meant so much to me, and to lose it would be a shame. I think it's important for us to preserve the foundational content of our communities.

transitional period i'd assume to make it easier for people to ease in, when the content they're expecting still flows in

It's basically how reddit got its start - as an aggregator of content that originated elsewhere.

I don't give a flying fuck.
