(This from guest blogger Alistair Alexander, who is on work experience with the Online desk this week): "Web filters used in American schools and libraries are screening out health information sites as well as porn, according to a study reported in the Washington Post. Tests using six popular software filters on 3,500 computers found that 24 per cent of health information sites were blocked if the filters were on their most restrictive setting.
But the researchers also found that filters were not the only barriers teenagers faced when searching the internet. "These kids can't spell," one of the authors said. "Thirty out of 132 search terms they used were misspelled. If you don't spell it correctly, you won't find anything like what you are looking for."
