i would probably agree that making some portions of the premium content free as a taste, or having a premium content-level thing as a freebie would help entice more subscribers, and would probably silence some of the complaints about content quality\quantity in general. but otoh i personally think this site's undergoing somewhat of a renaissance, especially after PAX East. i am a weirdo who thinks $5/mo is worth it just to support the guys and for the bombcast alone, though.
I'm honestly shocked that there hasn't been
A "free week/month trial for Giant Bomb Premium" sort of deal. Netflix and any other streaming video service uses it as a way to hook customers, so people are used to entering in their credit card number for the free trial. That way people can get a free looksies into what they're missing.
Released "Classic Videos" for free. Why not publicly share the three year old Random PC Game video for Police Quest: Swat? Is any of the premium members going to be upset over a three year old video being available for everyone? It would both entice freeloaders regular members to upgrade to view today's stuff and it would make the site seem more full.
