Sometimes (perhaps often) as technology advances we get too comfortable with what was. Cable TV has been around for a long time and an article like this awakens me to get back involved and get caught up. I found the article  informative, and felt it gave me confidence to talk with competing vendors in a more intelligent matter. Dealing with sales people will still be the major challenge, but perhaps it will help me get a better deal, at least temporarily.
The comment and explanation on pull and push technology added to my knowledge and I appreciate that.
