My good edit replies are never as long as my bad edit replies (I don't think a good edit needs much explanation).

Regardless, I do share some of your "spammy" concern (as I posted below about limits on these notifications over a certain period of time). The feature is likely to do good though there's definitely potential for it to irritate people, maybe even myself, if I get one for every edit I make by five different people. I think that's something Staff should consider when developing it more after this test (if it goes well). Perhaps a limitation on how many appreciations one people can give one user in some period of time could prevent this as well.
