My two cents: I actually think would be a fine idea for VI-C to be an affiliate and make bit off all the deals coming through the site. Maybe a dedicated forum with all the affiliate deals listed (not sure of the mechanics). I'd be happy to click through from VI-C for anything I'm interested in if it adds a bit to keep VI-C running.
I like the way you think!
As far as keeping the forum running, there's no danger there. The forum is not nearly as profitable as the estimates some people made a few months ago, but it is definitely in the black. (Not that I'm Mr. Moneybags, but even if it wasn't, the expenses are modest, so I could keep it afloat.) With that said, I think it's great how generous and community-minded people are when topics like this come up.
Anyway, regarding an affiliate structure, my fear with doing something like that is that some people would then believe I play favorites with the developers who participate, since I would directly benefit if they do well. That suspicion is a headache I don't want to deal with. Even as it is now, at least once a week someone will claim the forum favors Spitfire. (As if their $799/year banner ad is all it takes to buy my servitude. Don't get me wrong, my morals are most definitely for sale, but 800 bucks??? Please.
)
Even if perceived favoritism wasn't an issue, the bigger problem is that the income/work ratio would be too low. I'd have to email these guys to make deals, create custom links, make a payment structure, email again every time a new product is released or when a payment gets made ... ugh! The extra bucks would be nice, but ... the work! Plus, what do you want to bet that the developers who send me the biggest payouts would then want a discount on their banner ads? Ugh, ugh and ugh. It just isn't worth the headache, especially since my real gig is Realitone and composing, and VI-C already diverts enough time from those as it is.
So for now, at least, I'm just selling banner ads, since they're relatively easy. No doubt I'm leaving money on the table, but keeping life simple is my bigger goal at the moment.
