The Internet at different ages

The Internet is the best way to get information about anything. Nowadays it is essential in our society, because of the possibility of communicating with anyone, anytime and anywhere.

Firstly, the internet is good for all ages, because it has websites, entertainments and places for everyone, such as videogames, social networks, newspapers...

Furthermore, today the kids learn very fast and in very little time they are able to use new tecnologies, including the internet, very well, so the age at which kids start to use internet is earlier and earlier every day.

On the other hand, the internet can be dangerous for kids and young people because they need to have enough experience on internet to avoid websites promoting prejudice or to avoid being cheated by someone.  Therefore, the most important thing is to know your way around on internet.

Moreover, old people can have some difficulty handling new tecnologies, because they have never used anything similar and it's hard for them.

In conclusion, the internet can be used by anyone and we should use it, since it will be good for us, even though we must be very careful with websites.

Nice English!  Some of my suggestions are not necessary, but I think they have a more idiomatic style.
