Yoyogi is a tool that taps into your mastodon account (in your browser, locally) and shows messages by author / thread not as timeline. If you'd sort that like Fraidycat that would be a pretty interesting interface.

"Mastodon is just blogs and Google Reader, skinned to look like Twitter." That is pretty accurate, microblogging and following does what feedreading does too. In this case commenting is put at the exact same level as the orginal blogpost, akin to how I can reply to posts with a post of my own (like old trackbacks, now webmention)
