Everybody else is doing it and I wouldn't want to be left out. (Yes, I would jump off a bridge if everyone else did.) For those unfamiliar with 9rules, it is essentially a collection of well-written blogs (and yet they still let me in).
The value I hope this brings to the site is the increased audience that can foster greater, more thought-out discussion on the various web development topics that I normally post here. I also wish for it to drive me to generate more quality content for you. And that can only be a good thing!
