Ooh, RX. I haven't really used it much for quite a long time. When I did, I found it really, really interesting - but not terribly easy to use in reality. I just got confused a lot of the time. I still loved the ideas, but didn't quite see how to put them into practice.
Now it looks like a lot of people are very successful with RX in its various forms, and I definitely don't want to dissuade them. I don't even want to dissuade anyone who isn't currently using RX from giving it a try. I just want to avoid anyone else who finds it hard from feeling bad about themselves. I don't feel guilty for not embracing it wholeheartedly.
