Other things I pipe to #newsblur:
- #YouTube channels: user feeds & playlists, just add the URL as a new feed.
- #Newsletters: forwarding them to my personal newsblur email address treats them as one more feed.
- #Pinboard user feeds to track bookmarks added by people of interest (to me at least).
All the above are simple to setup and allow me to consolidate all incoming sources of interest to a single place.
I wonder how/if it would make sense to add #mastodon to the list of inputs
