It takes too much time and effort
It is just another information system
I am not getting enough knowledge in return
I do not know with whom to share the knowledge I feel insecure about how my knowledge might be received and understood I think the current channels to share knowledge are efficient enough I do not believe I can get good quality knowledge from there I am not being adequately rewarded or acknowledged I already have a good knowledge sharing network and I do not want to contribute to another I do not think my knowledge is important enough I am not sure whether my knowledge is reliable and do not want to risk losing my face I am afraid of criticism I do not want to share my knowledge with people I do not know well I am afraid of losing the ownership of the knowledge I am afraid that if I reveal what I know people will think I am not as proficient as they had expected I am afraid of losing the power and leverage brought by my knowledge
