I think this is an excellent business model for Mixergy. As a fan of Mixergy, I am happy that I have a weeks time to listen to the interviews before they go behind the subscription wall. Andrew, keep up the good work.
They're arguably worth it, but I can see folks with tight budgets not willing to pay that much for any content.
Also with so many good startup eyeballs I am curious if the sponsorship angle was considered, specifically from service providers. There seem to be a ton of lawyers & other products that would kill for eyeballs and ears in Andrew's market.
I'm a big fan as well but I still find this a bit startling. But I do appreciate as well the fact that you can watch interviews free for the first week. That is plenty -- he could have cranked that down to one day and personally I'd still find my way over there to watch/listen.
