With the recent updates to Pocket on iOS and Android, I wonder if there is any potential for adding a feed reader? A user could add their own feeds, use Pocket tagging or the new Lists and obviously save articles. Pocket has excellent syncing so all devices could be kept up to date with what’s been read and saved.
There are several open source options that could provide a basis like FreshRSS and could provide Mozilla with an additional revenue source, should they wish to.
