Use the keyword 'Internet' or 'internet' in our publications? So far all research papers I read and wrote I used the word 'Internet' instead of 'internet'. I did see an online article about the fact that people are using 'internet' more often nowadays, so should we still keep using it as before? 

My Take: the word 'Internet' is a name, that represents a technical infrastructure of many layers (networks, computers, programs, etc.) and its many users as a whole. So I think, the keyword 'Internet' should always be written with capital I. Am I wrong here?
People don't agree on this please see this wikipedia article on the capitalization of the word "internet".
