I like things like this because they're different. It feels like the sort of silly website you'd stumble across in the early 2000s. But I agree with some of the other posters that the limitation of choosing from canned phrases makes it feel boring almost immediately.

Something to consider: maybe being able to string random small-talk related words or phrases together, ala magnetic poetry[0], would result in more interesting chatter.
