Facebook Apps starting to open up new revenue streams

I just logged back into Biggest Brain for the first time in a while and found that they've now launched a premium version of the product that you can upgrade to right within the app. It's only $10/year - but given the marginal cost of nearly $0 that's pure profit; Kudos to Playfish for exploring this new revenue channel as an early mover. I'm a strong believer that during the course of 2008/2009 we will see significantly more advertising-supported businesses open up incremental channels besides banners, sponsorships and lead generation. I'd be curious to get my hands on some of the click rates for this attempt. As a marketer, i'm a big fan of having an upsell on the backend as it makes it easier for me to assign a budget towards getting more installs/ signups on the frontend.
