When I tried it, the response felt somewhat canned. Referencing as specifics only my place of work and the number of followers (I don't have a bio). Getting super generic praise does not feel that great.

It's a fun project (kudos for launching!), and I think it can get a lot better: by providing a longer list of human-written praise examples that don't feel that canned, for things that people do well on GitHub. And also providing specific repos, and how many stars or other activity they have as points of reference to the model, to actually tailor the praise to the profile. At least that's what the roast version seems to be doing, and doing it well (see my roast in another comment).
