After discovering RSS bridge; im shipping a lot of non-text via RSS too these days. Webcomics, my fiance’s art posts; and have been using it for a while to follow youtube accounts without a google account. (Possible without rss bridge).
Im also in general more prone to treat information as dispossable than you are I think. My general strategy avoids archiving; and instead keeping notes somewhere referencing the bits I think might be relevant again in the future.
