Thanks for the follow-up. IFrame had actually been there in version 1 but people use really non-standard stuff to break out of frames and some are not even aware of it because they use third-party frameworks. Screenshot + link to open in a new window actually started as a sort of a workaround but I think this allows people to focus more on first impressions instead of going into usability testing.
