They might be awesome, but unless you scroll down to the very bottom and notice a small note, you would think this a free service. I felt like being deceived and immediately closed the website after signup confirmation, when asked to enter credit card details.
I may have paid if I knew it upfront, but this kind of approach is so annoying, that I would prefer not to pay just because of that.
I think hasanove is talking about destroyallsoftware.com, which is a pay site, but it's hard to tell from the landing page.
I also think it's the response (i.e., railscasts.com/pro) that is being called awesome in the root comment, even though the wording is somewhat ambiguous.
