internet has more harmful materials than useful materials for youngsters

I think nothing in this world is useless or harmful for us. The main think, which makes things harmful for us is addiction and purpose of that thing. If you use internet for knowledge, networking and upgrading yourself, it would be more useful and less harmful for you. Every coin has its good and bad side.

i dont think so. the advantages of internet far outweigh the disadvantages even for children.

I believe children should only partake of 'gated communities' created and maintained by caregivers such as schools and parents that are most carefully supervised. Perhaps these 'gated communities' can be a selection of websites downloaded daily by the parents or caregivers held in a central computer. A browser allows for 'off-line viewing' on the hard disk. A firewall will prevent children from exiting the 'gated community' if the system is internet connected, or if the system isn't, it would be safer yet. * Children do need to learn how to use the Internet for their adult lives, but should do so in a protected environment. * You do not need the Internet to obtain the benefit of computing. In fact, you can set up a Linux computer with no connection to the Internet at all and still create a machine that is a learning tool. Office and educational software will help your student become a better learner. * If the Internet is needed for research, have your student download the data he or she needs using your computer under your supervision. Supervision is the key. Kids will not do questionable things with adult eyeballs on them.
