It's just over a year old. It's got amazing reviews. And who cares if it's gone free before? It wasn't yesterday, it is now, and I for one would never have known about it without this post. And to put it in perspective, this is the 3rd time it has gone free. These days that's nothing. Especially when it's been free for less than a week.
Thanks for posting the information about this. Best... Well, whatever. Sheesh.
