Not terribly surprised. When I tried the app out I didn't really get the appeal. It was like adding a comments section to existing news feeds and didn't provide enough tailoring or algorithmic understanding of reading habits to be a compelling offering.
Besides the fact that they were using a chrome embedded browser, meaning I couldn't even ad block on the sites I visited: which made the reading experience nearly impossible.
It had a built in reader mode to bypass the shitty ad-ridden websites. My favorite feature was the block words list. No more stories with the word “kardashian” for example.
The main attraction for me was the reader mode which blocks all ads, it also pushes similar articles from different new sites that I have never heard before (its a nice thing).
I found it worked pretty well, seemed to understand my interests pretty well after a couple days, when I usually don't feel that way, having tried many many similar apps. The chrome web view wasn't ideal, but I use pihole which helped :)
