I just subscribed on Christmas day with the 50% off deal and finally let the wife know about it today on our long drive back from her parent's.
So far, I am loving it, but will probably cancel next year since I really don't want to pay $100. I will probably be asking this same question next year the week before Christmas.
I had regret the first day as I do with most things that I spend money on, but after reading some premium articles each day and then reading the live chats with Sean and Nate on RSS, I am so glad I went ahead and took the deal. Maybe after a year I might just think that I can't live without it and will decide to fork over the dough that I get from the in-laws for Christmas every year.
