Happify anyone?

I love to follow many different blogs through Feedly.  It's a great way for me to pretend to stay on top of the websites I mean to visit but don't really have the time to.  One of the sites I follow is called Tiny Buddha:  Simple Wisdom for Complex Lives.  It is a great place for me to go and spend 15 minutes when I start to feel overwhelmed with life and all of my commitments.  Simple comics such as this one make me laugh and remind me not to take life so seriously:

Do More, Do Less form Dharma Doodles

Recently, an advertisment on Tiny Buddha struck my fancy so I clicked and ended up at Happify, a site that utilized activites to “build your happiness skills”.  I signed up for a free trial just to see what is was all about, because all of us want to be happier, right?  From my initial first clicks, the site seems to employ a lot of the same techniques that cognitive behavioral therapy uses to change someone’s thought processes through exercises and building new habits.  Has anyone used Happify or something similar?  I’d be curious to hear about your experiences.
