Technology and low SES

I very much enjoy all of the great aspects of technology we are learning in class, and I can't help but think that it can only help communicate with my students and their parents better, however, I teach at a school where very few families have a computer at home, and if they do have a computer, even few families have the internet. I could never count on my students or their family to utitlize blogs, posts their feelings on an online survey, check a website for homework assignments or even respone (or get) an email. It is so sad to me that the information superhighway is so limitless and useless to those who really can't afford to utilize it. It instantly puts SES students at a disadvantage.
