Hm.
It was said before, content is king. I think when you get into memberships there is a much higher expectation of content.
One thing I'd really like is an 'industry update.' Like, I don't have the time to read all the reviews, let alone the previews .... to have a 'briefing' every other week of what is going on in the industry in a distilled form and then links to each review (not preview) that would be, to me, value added. Ideally downloadable for viewing on an airplane. Don't have to get fancy, PDF is fine. Because lately time has been my biggest asset. I'd be less about the forum features and more about the review features.
