About once a month you can read this story from a new site/news organization. It's all good for ideas on how to go without cable, although the articles kind of write themselves after awhile.
I'm sure most people don't mention FTA, simply because FTA isn't as much an alternative to cable junkies ("Where will I get my reality shows filled with preening, future Z-list celebs?") as it is a great way to view programming that isn't available elsewhere. Beyond PBS and NBC, there's not a lot of overlap -- unlike Hulu or Netflix where you get a lot of the same shows.
