How does internet affect your identity?
The internet affects your identity in various ways.
Websites keep track on your ip address and some websites allow people to share information about themselves which they can keep for themselves.
Share your information only with friends. Be careful about who you share it with.
With the Ip address people can identify various things about the computer that is being used.
Your language tells people your identity. If you mean different languages language people can tell you are interested in that language and that is part of your identity. But if you go around saying, for example, "I'm going shopping going shopping" People will know you love to shop. Or if your always talking about the Internet people will know your way into the Internet.
I don't think that this would affect one's identity. If you switch to an other language that you know really well, you even think in that language, you don't translate. But I really don't see how this could affect your identity. My native language is dutch, second language is french, third language is English and the fourth language is German, but at the end I am still me and I'm flemish.
