Thanks for the feedback!

It could encourage people to read and engage with older stories, which currently just become a graveyard of old content.

I definitely think it will have this effect. It does on me, anyway. In developing the app, I find myself reading lots of old articles that I had missed the first time around - especially posts in languages that I can't read without translating. In my feed, I'm not going to take the time to translate a lot of those posts if I can't tell what the topic is, but Thoth gives me an English language summary, and that often spurs me to click through and translate the original post.

It needs a lot more work and adoption before the blockchain can deliver #lifetime-rewards at the scale we need, but the concept has definitely been proved at this point.

Feel free to check out the posting history for @thoth.test. I think it's already doing a reasonable job at selecting some good posts.
