Many people use the internet for work.
I know some technical people who are very frum, I wondered if I should send them an article on a topic we were researching. But they often use technical knowledge web sites which have some general advertising as well. And if you start surfing for answers to technical questions you are bound to see something that you should be not be.Anyway the link was something like ‘HTML5 Does not Suck’. I debated if i should send them the link like that.
Maybe I am naive but I decided not to. it happened to be a perfect link for us, but I wasn’t sure.
