A study by the Pew Internet Project has found that men and women use the Internet differently, but that about the same percentage of men and women in the US are serious internet users. It is no longer the case that men outnumber women on the Net - that trend is perhaps even reversing.
The research found that men value the net for the freedom it gives them to try new ways of doing things.
By contrast women like the opportunities the net gives them to make and maintain human connections.
