On a completely different note, I have something to recommend AVOIDING as you try to monetize the site. Popups. Even some -- ne, most -- of the good entertainment sites have succumbed to this temptation. I strongly recommend against it. While banner blindness remains a problem that can't be ignored, pop-up blocking is on the rise because pop ups are more annoying and more intrusive than banner ads ever were. Interstitials are almost as bad. Anything that gets in the way of being able to actually read the content is detrimental to building a loyal user base.
As I've said in the past, I recommend judicious placement of ads and links to other sites who share a cut of any proceeds with the referrer. Then, it's a matter of placing appropriate ads. There is a lot of SW-related stuff (esp. on eBay and Amazon) to which you can link, which speaks to the audience here. If we users can discipline ourselves to use this site as a click-through to these other sites, then revenue can be generated for the site just from our regular online buying habits. Seriously, if a link to Amazon guarantees a cut of the proceeds from a subsequent purchase, I'd be sure to not enter the URL directly and always go through a site I cared enough about. This merits more research as I don't fully understand the terms of these deals. But I do know that many sites have placed ads to several of the major online sites with such affiliate programs in place.
