Not sure if this is the best place for this, but i think i'll give it a shot. I've been running www.heartheissues.com for 7 months now, and things are going well. Traffic is steadily increasing, as are ad revenues, etc. however, to bring the site to the next level, i've realized "more of the same" won't work, (that is, just adding more and more pages of the same type of content). I need to add some type of content to the website that will have BROADER appeal, i.e. something that the more "mainstream" visitor would be interested in... i'm open to any ideas, from adding certain types of media (videos, images, etc) as i have plenty of hosting bandwidth to do it, or any other (hopefully specific) ideas that might come up.
I don´t know what you could do to expand, but have a suggestion about building on the content you have. Not exactly more of the same but the issues you address are quite explosive. You could get quite a buzz going if you invited a well known organisation or personality from each side of those debates to address a relevant question. As a bonus, look for those that have a strong internet presence and recommend that they link to their article from their site. Invite them to encourage their own members to give comments on your website. Each issue you have there is worth pages of content and if you stir the bottom a bit you´ll throw up enough debate to keep each topic fresh for ages. IMHO anyway.
