It is good to know. it is good for me to know .分别？

It is good to know your own weaknesses. = 知道自己的弱点是好事(人人皆适用
对我对你都是好事。) it is good for me to know my own weaknesses. = 知道自己的弱点对我来说是一件好事。(强调自己。) 简单嚟讲，It is good to know比较general，所以比较常用(google search 有成20

This is just used to tell others what is our main point. In your example
'It is good to know' mean know this is always good ''It is good for me to know'' mean I am just talking about myself It is simple! Just like the different beeen these o: John's mother can cook well Mother can cook well
本人认为头一句子"It is good to know" 祇是上文而已;其义思是"知道就好了"代表上文;而应该继续有下文. 至于第二句子 "It is good for me to know" 这句子也是上文而已;其义思是"我知道就好了"
而应该继续有下文. Yip
这件事是值得让人知道的 这件事让我知道是正确的（好的）
It is good to know.（适用对象是任何人）＝To know is good for everyone. It is good for me to know.（适用对象只限我一人）= To know is good for me. it是虚主词，不定词to know是delayed subject（延迟的主词）
it is good to know 带有你的意味存在 例如 It is good to know the information. 对我受用，同时也建议你可以去了解这个讯息 It is good for me to know the information. 这个讯息我来说很受用，强调"我" 但你不一定适合 Hope it is useful.
有me 就只有你知道，没有me 就人人都知道
