Internet is a great source of information, audio, transactions. It is also great for reading my own conversations over a decade ago.

Yet Internet can not replace real life friendship:

1) Typing is slower then saying.
2) Waiting for answers may take hours or days.
3) Our private problems become the property of Humanity and Eternity and our opponent in 2036 election.
4) Unfriendly forces may join any conversation.
