I teach college students and discourage their extreme over use of "great". It implies a comparison of qualities that they know little about as emergent professionals. EX: The director of the center was great. I would follow the suggestion of ptquilts. And if your ears sort of crinkle when you use well ..... then use good. This was a good conversation. We may cover the topic well and Kellogg Frosted Flakes are Grrrrrreat!
