There are a number of questions that are highly localised in nature, or might not fit at all with the current site.
The thought struck me that there may be scope for classified adverts (or possibly auctions) as a sister site in the same branding (once decided); or some kind of directory of related companies (studios/printing services/modelling agencies/etc) with the ability for people from here to add reviews. As an example, I'd rather sell a lens to someone with a reasonable reputation on here, then risk being fleeced by some scam on "another auction site"; Similarly, I'd rather buy form someone that hasn't asked a bunch load of questions about cleaning fungus from lenses...
Both options would allow for the site to fund itself to a certain degree (pay x to be a featured studio/pay to list/etc.), but I wonder how other people would feel about this? Do you think there would be scope for other things?
