r The phrase "Good. Good to know." appears to be a noncommittal or even sarcastic response. However, without additional context, it's challenging to discern the intended meaning. If we assume this is an evaluation or acknowledgment of something being acceptable or desirable, we must consider the complexities surrounding what constitutes "good" in various domains. This phrase might be used to convey ambivalence, skepticism, or a lack of emotional investment. Further clarification is necessary to fully understand the underlying sentiment.
