This question (5-star?) was also the first to my mind once I signed up and jumped into interaction with the app.

Given that each item shows a positive or negative number as its rating, it is unclear to me what the effect of a 5-, 3-, or 1- star ratings is against the net score for that item. I'm reasonably certain what the net effect will be, but it isn't totally obvious. The fact that it isn't so obvious is a friction point that makes me somewhat less likely to interact.

Using the familiar pattern of the binary up/down as arturadib has suggested (and taking a page from StackOverflow, Reddit, etc.) would make the interface much more familiar to me.

Though a binary up/down system would make this point irrelevant, I'll add it to the conversation anyway: It seems to me that over a long enough period of time, the rating for many items (using a 5 star system) will average near 3.

Congratulations on getting Listry out in the wild. Looking forward to witnessing future developments!
