Its not a bad thing if it connects people of different places even different country but nowadays the chatting cause problem in students study. They are chatting all time even all ??night also. In old days the chat means Email ?? bug now facebook, WhatsApp, Twitter.etc.It is information or enjoyable if u chat for a short period of time ? but who r going to teach the teenager.Its very usefull for me, I m staying outside my hometown so, I can share or receive any important ?? documents.
Use internet Chatting its usefull but in a limited way.
